Theoretical Challenges in Galaxy Formation
Thorsten Naab, Jeremiah P. Ostriker
Numerical simulations have become a major tool for understanding galaxy formation and evolution. Over the decades the field has made significant progress. It is now possible to sim…
The Galaxy--Halo Connection in High-Redshift Universe: Details and Evolution of Stellar-to-Halo Mass Ratios of Lyman Break Galaxies on CFHTLS Deep Fields
Shogo Ishikawa, Nobunari Kashikawa, Jun Toshikawa +5
We present the results of clustering analyses of Lyman break galaxies (LBGs) at , , and using the final data release of the Canada--France--Hawaii Telescope Legacy S…
Implications of galaxy buildup for putative IMF variations in massive galaxies
Kirsten Blancato, Shy Genel, Greg Bryan
Recent observational evidence for initial mass function (IMF) variations in massive quiescent galaxies at challenges the long-established paradigm of a universal IMF. While…
An Introduction to Gas Accretion onto Galaxies
M. E. Putman
Evidence for gas accretion onto galaxies can be found throughout the universe. In this chapter, I summarize the direct and indirect signatures of this process and discuss the prima…
HST/COS Observations of Ionized Gas Accretion at the Disk-halo Interface of M33
Y. Zheng, J. E. G. Peek, J. K. Werk +1
We report the detection of accreting ionized gas at the disk-halo interface of the nearby galaxy M33. We analyze HST/COS absorption-line spectra of seven ultraviolet-bright stars e…
The Complete Infrared View of Active Galactic Nuclei from the 70-month Swift/BAT Catalog
Kohei Ichikawa, Claudio Ricci, Yoshihiro Ueda +5
We systematically investigate the near- (NIR) to far-infrared (FIR) photometric properties of a nearly complete sample of local active galactic nuclei (AGN) detected in the Swift/B…
AGN Heating in Simulated Cool-Core Clusters
Yuan Li, Mateusz Ruszkowski, Greg L. Bryan
We analyze heating and cooling processes in an idealized simulation of a cool-core cluster, where momentum-driven AGN feedback balances radiative cooling in a time-averaged sense.…
OVI Emission From the Supernovae-regulated Interstellar Medium: Simulation Vs Observation
Miao Li, Greg Bryan, Jeremiah P. Ostriker
The OVI 1032, 1038Å doublet emission traces collisionally ionized gas with K, where the cooling curve peaks for metal-enriched plasma. This warm-hot phase i…
IC 3639 - A new bona fide Compton thick AGN unveiled by NuSTAR
Peter G. Boorman, P. Gandhi, D. Alexander +19
We analyse high-quality NuSTAR observations of the local (z = 0.011) Seyfert 2 active galactic nucleus (AGN) IC 3639, in conjunction with archival Suzaku and Chandra data. This pro…
Physics of Galactic Metals: Evolutionary Effects due to Production, Distribution, Feedback & Interaction with Black Holes
Ena Choi, Jeremiah P. Ostriker, Thorsten Naab +5
We ask how the inclusion of various physical heating processes due to the metal content of gas affect the evolution of massive galaxies and compute a suite of cosmological hydrodyn…
Quantifying Supernovae-Driven Multiphase Galactic Outflows
Miao Li, Greg L. Bryan, Jeremiah P. Ostriker
Galactic outflows are ubiquitously observed in star-forming disk galaxies and are critical for galaxy formation. Supernovae (SNe) play the key role in driving the outflows, but the…
Reverberation Mapping of Optical Emission Lines in Five Active Galaxies
M. M. Fausnaugh, C. J. Grier, M. C. Bentz +68
We present the first results from an optical reverberation mapping campaign executed in 2014, targeting the active galactic nuclei (AGN) MCG+08-11-011, NGC 2617, NGC 4051, 3C 382,…
New views of the distant stellar halo
Robyn E. Sanderson, Amy Secunda, Kathryn V. Johnston +1
Currently only a small number of Milky Way (MW) stars are known to exist beyond 100 kpc from the Galactic center. Though the distribution of these stars in the outer halo is believ…
The Properties of the Circumgalactic Medium in Red and Blue Galaxies: Results from the COS-GASS+COS-Halos Surveys
Sanchayeeta Borthakur, Timothy Heckman, Jason Tumlinson +7
We use the combined data from the COS-GASS and COS-Halos surveys to characterize the Circum-Galactic Medium (CGM) surrounding typical low-redshift galaxies in the mass range $\rm~M…
The Void Galaxy Survey: Photometry, structure and identity of void galaxies
B. Beygu, R. F. Peletier, J. M. van der Hulst +5
We analyze photometry from deep B-band images of 59 void galaxies in the Void Galaxy Survey (VGS), together with their near-infrared 3.6m and 4.5m Spitzer photometry. The VGS…
Modeling the gravitational potential of a cosmological dark matter halo with stellar streams
Robyn E. Sanderson, Johanna Hartke, Amina Helmi
Stellar streams result from the tidal disruption of satellites and star clusters as they orbit a host galaxy, and can be very sensitive probes of the gravitational potential of the…
The role of mergers and halo spin in shaping galaxy morphology
Vicente Rodriguez-Gomez, Laura V. Sales, Shy Genel +10
Mergers and the spin of the dark matter halo are factors traditionally believed to determine the morphology of galaxies within a CDM cosmology. We study this hypothesis by consi…
Beyond Jcrit: a critical curve for suppression of H2-cooling in protogalaxies
J. Wolcott-Green, Z. Haiman, G. L. Bryan
Suppression of H2-cooling in early protogalaxies has important implications for the formation of supermassive black holes seeds, the first generation of stars, and the epoch of rei…
Exploding Satellites -- The Tidal Debris of the Ultra-Faint Dwarf Galaxy Hercules
Andreas H. W. Küpper, Kathryn V. Johnston, Steffen Mieske +2
The ultra-faint satellite galaxy Hercules has a strongly elongated and irregular morphology with detections of tidal features up to 1.3 deg (3 kpc) from its center. This suggests t…
