Characterization and Photometric Performance of the Hyper Suprime-Cam Software Pipeline
Song Huang, Alexie Leauthaud, Ryoma Murata +9
The Subaru Strategic Program (SSP) is an ambitious multi-band survey using the Hyper Suprime-Cam (HSC) on the Subaru telescope. The Wide layer of the SSP is both wide and deep, rea…
Testing the presence of multiple photometric components in nearby early-type galaxies using SDSS
Semyeong Oh, Jenny E. Greene, Claire N. Lackner
We investigate two-dimensional image decomposition of nearby, morphologically selected early-type galaxies (ETGs). We are motivated by recent observational evidence of significant…
Luminous Red Galaxies in Clusters: Central Occupation, Spatial Distributions, and Mis-centering
Hanako Hoshino, Alexie Leauthaud, Claire Lackner +8
Luminous Red Galaxies (LRG) from the Sloan Digital Sky Survey are considered among the best understood samples of galaxies, and they are employed in a broad range of cosmological s…
The impact of cosmic variance on simulating weak lensing surveys
Arun Kannawadi, Rachel Mandelbaum, Claire Lackner
Upcoming weak lensing surveys will survey large cosmological volumes to measure the growth of cosmological structure with time and thereby constrain dark energy. One major systemat…
Understanding the Unique Assembly History of Central Group Galaxies
Benedetta Vulcani, Kevin Bundy, Claire Lackner +7
Central Galaxies (CGs) in massive halos live in unique environments with formation histories closely linked to that of the host halo. In local clusters they have larger sizes ($R_e…
Late-stage galaxy mergers in COSMOS to z~1
C. N. Lackner, J. D. Silverman, M. Salvato +14
The role of major mergers in galaxy and black hole formation is not well constrained. To help address this, we develop an automated method to identify late-stage galaxy mergers bef…
The Third Gravitational Lensing Accuracy Testing (GREAT3) Challenge Handbook
Rachel Mandelbaum, Barnaby Rowe, James Bosch +28
The GRavitational lEnsing Accuracy Testing 3 (GREAT3) challenge is the third in a series of image analysis challenges, with a goal of testing and facilitating the development of me…
Understanding black hole mass assembly via accretion and mergers at late times in cosmological simulations
Andrea Kulier, Jeremiah P. Ostriker, Priyamvada Natarajan +2
Accretion is thought to primarily contribute to the mass accumulation history of supermassive black holes throughout cosmic time. While this may be true at high redshifts, at lower…
The Effect of Environment on Discs and Bulges
C. N. Lackner, J. E. Gunn
We examine the changes in the properties of galactic bulges and discs with environment for a volume-limited sample of 12500 nearby galaxies from SDSS. We focus on galaxies with cla…
Building galaxies by accretion and in-situ star formation
C. N. Lackner, R. Cen, J. P. Ostriker +1
We examine galaxy formation in a cosmological AMR simulation, which includes two high resolution boxes, one centered on a 3 \times 10^14 M\odot cluster, and one centered on a void.…
Astrophysically Motivated Bulge-Disk Decompositions of SDSS Galaxies
C. N. Lackner, J. E. Gunn
We present a set of bulge-disk decompositions for a sample of 71,825 SDSS main-sample galaxies in the redshift range 0.003<z<0.05. We have fit each galaxy with either a de Vaucoule…
Calibrated Tully-Fisher relations for improved estimates of disk rotation velocities
R. Reyes, R. Mandelbaum, J. E. Gunn +2
In this paper, we derive scaling relations between photometric observable quantities and disk galaxy rotation velocity V_rot, or Tully-Fisher relations (TFRs). Our methodology is d…
Dissipational versus Dissipationless Galaxy Formation and the Dark Matter Content of Galaxies
Claire N. Lackner, Jeremiah P. Ostriker
We examine two extreme models for the build-up of the stellar component of luminous elliptical galaxies. In one case, we assume the build-up of stars is dissipational, with central…
Dynamical Tides in Rotating Planets and Stars
Jeremy Goodman, Claire Lackner
Tidal dissipation may be important for the internal evolution as well as the orbits of short-period massive planets--hot Jupiters. We revisit a mechanism proposed by Ogilvie and Li…
