The Gravity Collective: A Search for the Electromagnetic Counterpart to the Neutron Star-Black Hole Merger GW190814
Charles D. Kilpatrick, David A. Coulter, Iair Arcavi +79
We present optical follow-up imaging obtained with the Katzman Automatic Imaging Telescope, Las Cumbres Observatory Global Telescope Network, Nickel Telescope, Swope Telescope, and…
On the weak lensing masses of a new sample of galaxy groups
Elizabeth J. Gonzalez, Facundo Rodriguez, Manuel Merchán +6
Galaxy group masses are important to relate these systems with the dark matter halo hosts. However, deriving accurate mass estimates is particularly challenging for low-mass galaxy…
Measuring the surface mass density ellipticity of redMaPPer galaxy clusters using weak-lensing
Elizabeth J. Gonzalez, Martin Makler, Diego Garcia Lambas +5
In this work we study the shape of the projected surface mass density distribution of galaxy clusters using weak-lensing stacking techniques. In particular, we constrain the averag…
Weak lensing analysis of galaxy pairs using CS82 data
Elizabeth J. Gonzalez, Facundo Rodriguez, Diego García Lambas +6
In this work we analyze a sample of close galaxy pairs (relative projected separation kpc and relative radial velocities km s) using a weak lensing analy…
Compact Groups analysis using weak gravitational lensing II: CFHT Stripe 82 data
Martín Chalela, Elizabeth J. Gonzalez, Martín Makler +4
In this work we present a lensing study of Compact Groups (CGs) using data obtained from the high quality Canada-France-Hawaii Telescope Stripe 82 Survey. Using stacking techniques…
Do satellite galaxies trace matter in galaxy clusters?
Chunxiang Wang, Ran Li, Liang Gao +9
The spatial distribution of satellite galaxies encodes rich information of the structure and assembly history of galaxy clusters. In this paper, we select a redMaPPer cluster sampl…
Probing galaxy assembly bias with LRG weak lensing observations
A. Niemiec, E. Jullo, A. D. Montero-Dorta +9
In Montero-Dorta et al. 2017, we show that luminous red galaxies (LRGs) from the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS) at can be divided into two grou…
On Mass Concentrations & Magnitude Gaps of Galaxy Systems in the CS82 Survey
André Z. Vitorelli, Eduardo S. Cypriano, Martín Makler +3
Galaxy systems with large magnitude gaps - defined as the difference in magnitude between the central galaxy and the brightest satellite in the central region - have been claimed t…
Weak-lensing calibration of a stellar mass-based mass proxy for redMaPPer and Voronoi Tessellation clusters in SDSS Stripe 82
Maria E. S. Pereira, Marcelle Soares-Santos, Martin Makler +9
We present the first weak lensing calibration of , a new galaxy cluster mass proxy corresponding to the total stellar mass of red and blue members, in two cluster sample…
Morpho-z: improving photometric redshifts with galaxy morphology
John Y. H. Soo, Bruno Moraes, Benjamin Joachimi +10
We conduct a comprehensive study of the effects of incorporating galaxy morphology information in photometric redshift estimation. Using machine learning methods, we assess the cha…
Stellar-to-halo mass relation of cluster galaxies
Anna Niemiec, Eric Jullo, Marceau Limousin +12
In the hierarchical formation model, galaxy clusters grow by accretion of smaller groups or isolated galaxies. During the infall into the centre of a cluster, the properties of acc…
The abundance of compact quiescent galaxies since z ~ 0.6
Aldée Charbonnier, Marc Huertas-Company, Thiago S. Gonçalves +12
We set out to quantify the number density of quiescent massive compact galaxies at intermediate redshifts. We determine structural parameters based on i-band imaging using the CFHT…
Lensing is Low: Cosmology, Galaxy Formation, or New Physics?
Alexie Leauthaud, Shun Saito, Stefan Hilbert +19
We present high signal-to-noise galaxy-galaxy lensing measurements of the BOSS CMASS sample using 250 square degrees of weak lensing data from CFHTLenS and CS82. We compare this si…
The Mass-Concentration Relation and the Stellar-to-Halo Mass Ratio in the CFHT Stripe 82 Survey
Huanyuan Shan, Jean-Paul Kneib, Ran Li +8
We present a new measurement of the mass-concentration relation and the stellar-to-halo mass ratio over the halo mass range to . To achi…
The SOAR Gravitational Arc Survey - I: Survey overview and photometric catalogs
Cristina Furlanetto, Basilio X. Santiago, Martin Makler +10
We present the first results of the SOAR (Southern Astrophysical Research) Gravitational Arc Survey (SOGRAS). The survey imaged 47 clusters in two redshift intervals centered at $z…
