A study of the color diversity around maximum light in Type Ia supernovae
Regis Cartier, Francisco Forster, Paolo Coppi +5
From a sample of 12 well-observed Type Ia supernovae, we find clear evidence of correlations between early phase (U-B), (V-R), and (V-I) colors and the velocity shifts of the [Fe I…
The Sudden Death of the Nearest Quasar
Kevin Schawinski, Daniel A. Evans, Shanil Virani +13
Galaxy formation is significantly modulated by energy output from supermassive black holes at the centers of galaxies which grow in highly efficient luminous quasar phases. The tim…
Overview of EXIST mission science and implementation
J. Grindlay, N. Gehrels, J. Bloom +14
The Energetic X-ray Imaging Survey Telescope (EXIST) is designed to i) use the birth of stellar mass black holes, as revealed by cosmic Gamma-Ray Bursts (GRBs), as probes of the ve…
Black hole growth and host galaxy morphology
Kevin Schawinski, C. Megan Urry, Shanil Virani +11
We use data from large surveys of the local Universe (SDSS+Galaxy Zoo) to show that the galaxy-black hole connection is linked to host morphology at a fundamental level. The fracti…
Galaxy Zoo: The fundamentally different co-evolution of supermassive black holes and their early- and late-type host galaxies
Kevin Schawinski, C. Megan Urry, Shanil Virani +18
We use data from the Sloan Digital Sky Survey and visual classifications of morphology from the Galaxy Zoo project to study black hole growth in the nearby Universe (z < 0.05) and…
The EXIST view of Super-Massive Black Holes in the Universe
Roberto Della Ceca, Gabriele Ghisellini, Gianpiero Tagliaferri +9
With its large collection area, broad-band energy coverage from optical/NIR (0.3 to 2.2 micron) to soft/hard X-ray (0.1-600 keV), all-sky monitoring capability, and on-board follow…
