The locations of features in the mass distribution of merging binary black holes are robust against uncertainties in the metallicity-dependent cosmic star formation history
L. A. C. van Son, S. E. de Mink, M. Chruslinska +3
New observational facilities are probing astrophysical transients such as stellar explosions and gravitational wave (GW) sources at ever increasing redshifts, while also revealing…
How to measure galaxy star-formation histories I: Parametric models
A. C. Carnall, J. Leja, B. D. Johnson +3
Parametric models for galaxy star-formation histories (SFHs) are widely used, though they are known to impose strong priors on physical parameters. This has consequences for measur…
The Electromagnetic Counterpart of the Binary Neutron Star Merger LIGO/VIRGO GW170817. VII. Properties of the Host Galaxy and Constraints on the Merger Timescale
P. K. Blanchard, E. Berger, W. Fong +21
We present the properties of NGC 4993, the host galaxy of GW170817, the first gravitational wave (GW) event from the merger of a binary neutron star (BNS) system and the first with…
Extended main sequence turnoffs in open clusters as seen by Gaia -- II. The enigma of NGC 2509
M. de Juan Ovelar, S. Gossage, S. Kamann +5
We investigate the morphology of the colour-magnitude diagram (CMD) of the open cluster NGC 2509 in comparison with other Galactic open clusters of similar age using Gaia photometr…
Stellar populations of stellar halos: Results from the Illustris simulation
B. A. Cook, C. Conroy, A. Pillepich +1
The influence of both major and minor mergers is expected to significantly affect gradients of stellar ages and metallicities in the outskirts of galaxies. Measurements of observed…
The information content of stellar halos: Stellar population gradients and accretion histories in early-type Illustris galaxies
B. A. Cook, C. Conroy, A. Pillepich +2
Long dynamical timescales in the outskirts of galaxies preserve the information content of their accretion histories, for example in the form of stellar population gradients. We pr…
Mapping the Dark Matter From UV Light at High Redshift: An Empirical Approach to Understand Galaxy Statistics
K. -S. Lee, M. Giavalisco, C. Conroy +5
We present a simple formalism to interpret two galaxy statistics, the UV luminosity function and two-point correlation functions for star-forming galaxies at z~4, 5, 6 in the conte…
Galaxy Luminosity Functions to z~1: DEEP2 vs. COMBO-17 and Implications for Red Galaxy Formation
S. M. Faber, C. N. A. Willmer, C. Wolf +28
The DEEP2 and COMBO-17 surveys are used to study the evolution of the luminosity function of red and blue galaxies to . Schechter function fits show that, since ,…
No peaks without valleys: The stable mass transfer channel for gravitational-wave sources in light of the neutron star-black hole mass gap
L. A. C. van Son, S. E. de Mink, M. Renzo +6
Gravitational-wave (GW) detections are starting to reveal features in the mass distribution of double compact objects. The lower end of the black hole (BH) mass distribution is esp…
Towards the 2020 vision of the baryon content of galaxy groups and clusters
A. Kravtsov, A. Gonzalez, A. Vikhlinin +12
Groups and clusters of galaxies occupy a special position in the hierarchy of large-scale cosmic structures because they are the largest and the most massive (from ~10^13 Msun to o…
Comparison of Stellar Population Model Predictions Using Optical and Infrared Spectroscopy
C. M. Baldwin, R. M. McDermid, H. Kuntschner +2
We present Gemini/GNIRS cross-dispersed near-infrared spectra of 12 nearby early-type galaxies, with the aim of testing commonly used stellar population synthesis models. We select…
The DEEP2 Galaxy Redshift Survey: The Galaxy Luminosity Function to z ~ 1
C. N. A. Willmer, S. M. Faber, D. C. Koo +20
The evolution of the B-band galaxy luminosity function is measured using a sample of more than 11,000 galaxies with spectroscopic redshifts from the DEEP2 Redshift Survey. The rest…
