ALMA Imaging of HCN, CS and dust in Arp 220 and NGC 6240
Nick Scoville, Kartik Sheth, Fabian Walter +19
We report ALMA Band 7 (350 GHz) imaging at 0.4 - 0.6arcsec resolution and Band 9 (696 GHz) at ~0.25arcsec resolution of the luminous IR galaxies Arp 220 and NGC 6240. The long wave…
Synthetic Galaxy Images and Spectra from the Illustris Simulation
Paul Torrey, Gregory F. Snyder, Mark Vogelsberger +10
We present our methods for generating a catalog of 7,000 synthetic images and 40,000 integrated spectra of redshift z = 0 galaxies from the Illustris Simulation. The mock data prod…
The Formation of Massive, Compact Galaxies at z=2 in the Illustris Simulation
Sarah Wellons, Paul Torrey, Chung-Pei Ma +13
Massive, quiescent galaxies at high redshift have been found to be considerably more compact than galaxies of similar mass in the local universe. How these compact galaxies formed…
The colors of satellite galaxies in the Illustris Simulation
Laura V. Sales, Mark Vogelsberger, Shy Genel +8
Observationally, the fraction of blue satellite galaxies decreases steeply with host halo mass, and their radial distribution around central galaxies is significantly shallower in…
Formation of massive protostars in atomic cooling haloes
Fernando Becerra, Thomas H. Greif, Volker Springel +1
We present the highest-resolution three-dimensional simulation to date of the collapse of an atomic cooling halo in the early Universe. We use the moving-mesh code arepo with the p…
The star formation main sequence and stellar mass assembly of galaxies in the Illustris simulation
Martin Sparre, Christopher C. Hayward, Volker Springel +6
Understanding the physical processes that drive star formation is a key challenge for galaxy formation models. In this article we study the tight correlation between the star forma…
