See the Sound: Transients in the Local Universe
Mansi M. Kasliwal
10:45am|Bloomberg Hall Lecture Hall

The advent of wide-field synoptic imaging has re-invigorated the venerable field of time domain astronomy. Our framework of optical transients no longer has a wide six-magnitude luminosity "gap" between the brightest novae and faintest supernovae...

Forming Massive Galaxies
Pieter van Dokkum
12:00am|Bloomberg Hall Lecture Hall

The talk begins in 2005, with the unexpected discovery that massive early-type galaxies were extremely compact at redshifts z~2. It is now thought that the remarkable size growth of these galaxies from z=2 to z=0 is largely due to minor mergers; the...

The Social Life of Spacecraft: How sociotechnical organization matters in scientific work
Janet Vertesi
12:00am|Bloomberg Hall Lecture Hall

What role does social organization play in the conduct and practice of science? In this talk, I explore how the social and technical organization of scientific collaborations matters for the production of team solidarities, data sharing norms, and...

Cosmological Calorimetry: The nature of the intergalactic medium and the photon underproduction crisis
12:00am|Bloomberg Hall Lecture Hall
The Lyman alpha forest remains one of the most robust predictions of cosmological hydrodynamic simulations. Lyman alpha absorption lines have been used for decades to trace cosmic structures that -- only recently, with the exquisite sensitivity...

Stellar Forensics with Explosions: Supernovae, Gamma-Ray Bursts, and their Environments
Maryam Modjaz
12:00am|Bloomberg Hall Lecture Hall

Nature's two magnificent explosions, long-duration gamma-ray bursts (GRBs) and stripped-envelope supernovae (SNe), are both products of collapsing massive stars. Yet, over the last 15 years, we have not determined the detailed make-up of the stellar...
