Reaching for the Edge I: Probing the Outskirts of Massive Galaxies with HSC, DECaLS, SDSS, and Dragonfly
Jiaxuan Li, Song Huang, Alexie Leauthaud +9
The outer light (stellar halos) of massive galaxies has recently emerged as a possible low scatter tracer of dark matter halo mass. To test the robustness of outer light measuremen…
Stellar and Weak Lensing Profiles of Massive Galaxies in the Hyper-Suprime Cam Survey and in Hydrodynamic Simulations
Felipe Ardila, Song Huang, Alexie Leauthaud +11
We perform a consistent comparison of the mass and mass profiles of massive () central galaxies at z~0.4 from deep Hyper Suprime-Cam (HSC) observation…
Galaxy-Galaxy Lensing in HSC: Validation Tests and the Impact of Heterogeneous Spectroscopic Training Sets
Joshua S. Speagle, Alexie Leauthaud, Song Huang +9
Although photometric redshifts (photo-z's) are crucial ingredients for current and upcoming large-scale surveys, the high-quality spectroscopic redshifts currently available to tra…
Deep+Wide Lensing Surveys will Provide Exquisite Measurements of the Dark Matter Halos of Dwarf Galaxies
Alexie Leauthaud, Sukhdeep Singh, Yifei Luo +5
The advent of new deep+wide photometric lensing surveys will open up the possibility of direct measurements of the dark matter halos of dwarf galaxies. The HSC wide survey will be…
Weak Lensing Reveals a Tight Connection Between Dark Matter Halo Mass and the Distribution of Stellar Mass in Massive Galaxies
Song Huang, Alexie Leauthaud, Andrew Hearin +9
Using deep images from the Hyper Suprime-Cam (HSC) survey and taking advantage of its unprecedented weak lensing capabilities, we reveal a remarkably tight connection between the s…
Shocked POststarburst Galaxy Survey. III. The Ultraviolet Properties of SPOGs
Felipe Ardila, Katherine Alatalo, Lauranne Lanz +11
The Shocked POststarburst Galaxy Survey (SPOGS) aims to identify galaxies in the transitional phase between actively star-forming and quiescence with nebular lines that are excited…
The XXL survey XV: Evidence for dry merger driven BCG growth in XXL-100-GC X-ray clusters
S. Lavoie, J. P. Willis, J. Democles +33
The growth of brightest cluster galaxies is closely related to the properties of their host cluster. We present evidence for dry mergers as the dominant source of BCG mass growth a…
Shocked POststarburst Galaxy Survey II: The Molecular Gas Content and Properties of a Subset of SPOGs
Katherine Alatalo, Ute Lisenfeld, Lauranne Lanz +8
We present CO(1-0) observations of objects within the Shocked POststarburst Galaxy Survey taken with the Institut de Radioastronomie Millimetrique (IRAM) 30m single dish and the Co…
The XXL Survey: VI. The 1000 brightest X-ray point sources
S. Fotopoulou, F. Pacaud, S. Paltani +36
X-ray extragalactic surveys are ideal laboratories for the study of the evolution and clustering of active galactic nuclei (AGN). The XXL Survey spans two fields of a combined 50 $…
The XXL survey XIV. AAOmega redshifts for the southern XXL field
C. Lidman, F. Ardila, M. Owers +15
We present a catalogue containing the redshifts of 3,660 X-ray selected targets in the XXL southern field. The redshifts were obtained with the AAOmega spectrograph and 2dF fibre p…
The XXL Survey. II. The bright cluster sample: catalogue and luminosity function
F. Pacaud, N. Clerc, P. A. Giles +40
Context. The XXL Survey is the largest survey carried out by the XMM-Newton satellite and covers a total area of 50 square degrees distributed over two fields. It primarily aims at…
