Physics and Astronomy Colloquium: The Life and Death of Massive Galaxies

The average rate at which galaxies are forming stars in the Universe has decreased by more than an order of magnitude over the last 10 billion years. Understanding why certain galaxies shut off their star formation activity, while others do not is one of the key unanswered questions in astrophysics today. Observations in the local Universe suggest that the mechanism responsible for quenching star formation in galaxies may be intimately linked to both their mass assembly and their structural transformation from disks to spheroids. In order to test quenching scenarios, however, it is vital to look beyond the local Universe and identify the first generation of quiescent, "red and dead" galaxies at high redshift. I will discuss my work studying the rest-frame visible morphologies of the first massive systems to appear on the quiescent "red sequence" at redshifts z>1, when the universe was less than half its current age. Interestingly, a significant fraction (~30%) have morphologies dominated by massive exponential disks. The persistence of massive disks, long after star formation has ceased, implies that in at least some cases quenching precedes morphological transformation. I will examine what constraints these observations place on the mechanisms responsible for quenching the first generation of passive galaxies at z~2 and discuss them in context with an emerging picture of massive galaxy formation and evolution. Refreshments will be served in CP 179 at 3:15 PM

ANASTAMOSING CHANNELS

Recently published in Earth Surface Processes & Landforms: Anastamosing Channels in the Lower Neches River Valley, Texas. The abstract is below: 

 

Active and semi-active anastomosing Holocene channels upstream of the delta in the lower valley of the meandering Neches River in southeast Texas represent several morphologically distinct and hydrologically independent channel systems. These appear to have a common origin as multi-thread crevasse channels strongly influenced by antecedent morphology. Levee breaching leads to steeper cross-valley flows toward floodplain basins associated with Pleistocene meander scars, creating multi-thread channels that persist due to additional tributary contributions and ground water inputs. Results are consistent with the notion of plural systems where main channels, tributaries, and sub-channels may have different morphologies and hydrogeomorphic functions. The adjacent Trinity and Sabine Rivers have similar environmental controls, yet the Trinity lacks evidence of extensive anastomosing channels on its floodplain, and those of the Sabine appear to be of different origin. The paper highlights the effects of geographical and historical contingency and hydrological idiosyncrasy.

 

HURRI-CANE TOADS!

 

I recently watched an episode of the Syfy Channel’s post-apocalyptic zombie show Z-Nation. The human survivors were making their way across the U.S. Midwest when a massive tornado spun up, picking up zombies and flinging them all over the place.

“Is that what I think it is?” asks one character, observing the oncoming cyclone of the undead. “It ain’t sharks,” says his companion. This is, of course, a reference to the infamous “Sharknado” movie in which a tornado at sea (technically a waterspout, I reckon) sucks up a bunch of sharks and blows them into Los Angeles. Sharknado is, by all accounts, a thoroughly ridiculous movie with no scientific validity.

The tornado in the background is just about to suck up these flesh-eating freaks from beyond the grave to form an un-deadly Z-nado!

BLACK FLAGS, ISIS “SWAG” & JIHADI RAP: MARKETING MILITANCY AFTER THE ARAB SPRING

August 2014: my activist, academic, and journalistic lives collided in a digitized split-second. Online, I came face-to-surreal-face with ISIS’ execution of a colleague, terrified for the haunting film’s second captive—a friend. Although immersed professionally and personally in graphic image wars, this video proved especially disturbing, but why? Marketing’s analytical frame, strategic deployment of popular culture, and the intended audience of young, digitally networked “global citizens” best contextualizes the ISIS phenomenon: a propaganda blitzkrieg rooted in commodified rebellion’s consumption (Che t-shirts), not theology. ISIS exemplifies the paradoxical power of cultural production in contemporary geopolitical combat theater—war’s increasingly symbolic terrain.

Amanda E. Rogers holds a PhD from Emory (2013). She is an academic, journalist, artist, and political analyst whose work appears in numerous forums, including the BBC, Al-Jazeera, and the New York Times. Her forthcoming monograph, Semiotics of Rebellion From Morocco to Egypt: Advertising Revolution and Marketing Allegiance, focuses on the critical use of politicized cultural discourse for international alliances, regional stability, and intra nation-state image warfare.

Linguistics Seminar: "Embodiment and Competition: Two Factors in the Organization of Languages"

For decades, many linguists have framed the study of language in terms of a language faculty, a specialized cognitive ‘organ’ unique to humans.  In the last decade, even the most stalwart proponents of this view have come to acknowledge the existence of other factors in the organization of human languages. In this talk, I will concentrate on two of these factors, embodiment and competition, drawing examples from the morphology of spoken and signed languages. Neither is unique to language, nor especially human or cognitive in nature.  Their role in the structuring of languages points to a new research paradigm in the study of language, in which no single factor is privileged and the importance of any one of them is gauged only by the insights it provided, not by its uniqueness to language.

Public Lecture: "Sign Languages of Israel"

Israel is a microcosm of the sign language world.  Within a country about equal in area to New Jersey, Israel contains both a widely dispersed deaf community sign language used in schools, Israeli Sign Language, and a number of much smaller village sign languages, each confined to a single community and used only within its confines.  Our research team was formed to study Israeli Sign Language, but we have also spent the last decade studying and documenting the sign language of the Bedouin village of Al-Sayyid, located near Be’er Sheva, the ancestral home of Abraham.  I will compare the history and structure of these two languages and show how the study of their emergence has provided a variety of insights into language and human nature.

Katherine Behar Opening Reception

Brooklyn-based interdisciplinary artist Katherine Behar will present E-Waste, an exhibition of new work at UK’s Tuska Center for Contemporary Art. 

Behar’s installation centers on a new series of sculptures inspired by a science fiction scenario in which commonplace USB devices continue working, long after the humans they were designed to serve have gone extinct. The gadgets are transformed into mutant fossils, encased in stone with lights blinking, speakers chirping, and fans spinning eternally. The exhibition also includes a video series, Modeling Big Data, in which the artist inhabits an obese, over-grown data body, to humorous and poignant effect. 

Behar’s work challenges digital culture’s intense escalation of productivity. Wavering between poetry and parody, her works elicit sympathy for the devices we exploit, suggesting that we ourselves are becoming increasingly device-like: ensnared in compulsory productivity, whether “working” in the traditional sense for our own gain, or generating value for distant corporations each time we search the web or click “like.” Combining machine-made, handmade, and organic forms, including a “fossilized” 3D printer, E-Waste offers a physical parallel to the excesses of big data, highlighting the counterpart surplus of consumer media artifacts, and drawing attention to its environmental impact. 

E-Waste is co-produced by the College of Fine Arts and the College of Arts and Sciences, and supported in part by a PSC-CUNY Award, jointly funded by The Professional Staff Congress and The City University of New York.

A&S Distinguished Professor Lecture

This Spanish–Moroccan war, known in Spain as the War of Africa, was a colonial military operation that resulted in the surrender of the city of Tetouan. A political victory with no tangible gains, the African War formed part of a persuasive rhetoric and a stirring propaganda used by the Spanish government to heighten the national pride of the people. The patriotic delirium surrounding this war marks the beginnings —and also the death throes— of Spanish colonialism on Moroccan territory in modern times. Spain’s military intervention in Morocco inspired an abundant literature whose aim was to glorify the war. Professor Rueda examines one-act plays on the topic of the War of Africa to reveal how war was staged and orchestrated politically through theatrical and musical performance. Burlesque musical re-presentations of the War of Africa reinforce collective yet conflictive notions of national identity, still unresolved at the threshold of Modernity, while exposing Spain’s impracticable political aspirations to regain its lost colonial power and the nation’s hesitancy to refashion itself as a modern nation.
