Milky Way Satellite Census. II. Galaxy--Halo Connection Constraints Including the Impact of the Large Magellanic Cloud
E. O. Nadler, R. H. Wechsler, K. Bechtol +63
The population of Milky Way (MW) satellites contains the faintest known galaxies and thus provides essential insight into galaxy formation and dark matter microphysics. Here we com…
Barry and the BAO Model Comparison
Samuel R. Hinton, Cullan Howlett, Tamara M. Davis
We compare the performance of four state-of-the-art models for extracting isotropic measurements of the Baryon Acoustic Oscillation (BAO) scale. To do this, we created a new, publi…
The Mystery of Photometric Twins DES17X1boj and DES16E2bjy
M. Pursiainen, C. Gutierrez, P. Wiseman +80
We present an analysis of DES17X1boj and DES16E2bjy, two peculiar transients discovered by the Dark Energy Survey (DES). They exhibit nearly identical double-peaked light curves wh…
Can redshift errors bias measurements of the Hubble Constant?
Tamara M. Davis, Samuel R. Hinton, Cullan Howlett +1
Redshifts have been so easy to measure for so long that we tend to neglect the fact that they too have uncertainties and are susceptible to systematic error. As we strive to measur…
4MOST: Project overview and information for the First Call for Proposals
R. S. de Jong, O. Agertz, A. Agudo Berbel +335
We introduce the 4-metre Multi-Object Spectroscopic Telescope (4MOST), a new high-multiplex, wide-field spectroscopic survey facility under development for the four-metre-class Vis…
CIV Black Hole Mass Measurements with the Australian Dark Energy Survey (OzDES)
J. K. Hoormann, P. Martini, T. M. Davis +67
Black hole mass measurements outside the local universe are critically important to derive the growth of supermassive black holes over cosmic time, and to study the interplay betwe…
