Generation of massive stellar black holes by rapid gas accretion in primordial dense clusters
Zacharias Roupas, Demosthenes Kazanas
Supernova theory suggests that black holes of a stellar origin cannot attain masses in the range of 50-135 solar masses in isolation. We argue here that this mass gap is filled in…
A Catalog of Emission-Line Galaxies from the Faint Infrared Grism Survey: Studying Environmental Influence on Star Formation
John Pharo, Sangeeta Malhotra, James E. Rhoads +18
We present a catalog of 208 Emission Line Galaxies (ELG) selected from 1D slitless spectroscopy obtained using Hubble's WFC3 G102 grism, as part of the Faint Infrar…
Rest-frame UV and optical emission line diagnostics of ionised gas properties: a test case in a star-forming knot of a lensed galaxy at z~1.7
Ayan Acharyya, Lisa J. Kewley, Jane R. Rigby +7
We examine the diagnostic power of rest-frame ultraviolet (UV) nebular emission lines, and compare them to more commonly used rest-frame optical emission lines, using the test case…
Near-Infrared Spectroscopy of Galaxies During Reionization: Measuring CIII] in a Galaxy at
Taylor A. Hutchison, Casey Papovich, Steven L. Finkelstein +9
We present Keck/MOSFIRE -band spectroscopy targeting CIII] 1907,1909 in a galaxy previously identified via Ly emission. We detect strong line emission at $1…
The Extragalactic Gamma-Ray Background from Core Dominated Radio Galaxies
Floyd W. Stecker, Chris R. Shrader, Matthew. A. Malkan
Recent radio surveys have discovered a large number of low luminosity core dominated radio galaxies that are much more abundant than those at higher luminosities. These objects wil…
Cosmic Pathways for Compact Groups in the Milli-Millennium Simulation
P. Tzanavaris, S. C. Gallagher, S. Ali +3
We detected 10 compact galaxy groups (CGs) at in the semi-analytic galaxy catalog of Guo et al. (2011) for the milli-Millennium Cosmological Simulation (sCGs in mGuo2010a). W…
