UV to IR Luminosities and Dust Attenuation Determined from ~4000 K-Selected Galaxies at 1<z<3 in the ZFOURGE Survey
Ben Forrest, Kim-Vy H. Tran, Adam R. Tomczak +22
We build a set of composite galaxy SEDs by de-redshifting and scaling multi-wavelength photometry from galaxies in the ZFOURGE survey, covering the CDFS, COSMOS, and UDS fields. Fr…
Infall, the Butcher-Oemler Effect, and the Descendants of Blue Cluster Galaxies at z~0.6

Using wide-field HST/WFPC2 imaging and extensive Keck/LRIS spectroscopy, we present a detailed study of the galaxy populations in MS2053--04, a massive, X-ray luminous cluster at z…
The Contribution of Halos with Different Mass Ratios to the Overall Growth of Cluster-Sized Halos
Doron Lemze, Marc Postman, Shy Genel +39
We provide a new observational test for a key prediction of the ÎCDM cosmological model: the contributions of mergers with different halo-to-main-cluster mass ratios to cluster-si…
The Nature of E+A Galaxies in Intermediate Redshift Clusters
Kim-Vy Tran, Marijn Franx, Garth Illingworth +2
[Abridged] Combining HST/WFPC2 mosaics with extensive ground-based spectroscopy, we study the nature of E+A galaxies in three intermediate redshift clusters (z=0.33, 0.58, & 0.83).…
Three Gravitationally Lensed Supernovae Behind CLASH Galaxy Clusters
Brandon Patel, Curtis McCully, Saurabh W. Jha +42
We report observations of three gravitationally lensed supernovae (SNe) in the Cluster Lensing And Supernova survey with Hubble (CLASH) Multi-Cycle Treasury program. These objects,…
Cluster Lensing And Supernova survey with Hubble (CLASH): An Overview
Marc Postman, Dan Coe, Narciso Benitez +42
The Cluster Lensing And Supernova survey with Hubble (CLASH) is a 524-orbit multi-cycle treasury program to use the gravitational lensing properties of 25 galaxy clusters to accura…
The Hubble Constant from the HST Key Project on the Extragalactic Distance Scale
Laura Ferrarese, Brad Gibson, Daniel Kelson +14
The final efforts of the HST Key Project on the Extragalactic Distance Scale are presented. Four distance indicators, the Surface Brightness Fluctuation method, the Fundamental Pla…
ASKAP J144834-685644: a newly discovered long period radio transient detected from radio to X-rays
Akash Anumarlapudi, David L. Kaplan, Nanda Rea +13
Long-period radio transients (LPTs) are an emerging group of radio transients that show periodic polarized radio bursts with periods varying from a few minutes to a few hours. Fewe…
CLASH: Precise New Constraints on the Mass Profile of Abell 2261
Dan Coe, Keiichi Umetsu, Adi Zitrin +43
We precisely constrain the inner mass profile of Abell 2261 (z=0.225) for the first time and determine this cluster is not "over-concentrated" as found previously, implying a forma…
CLASH: Complete Lensing Analysis of the Largest Cosmic Lens MACS J0717.5+3745 and Surrounding Structures
Elinor Medezinski, Keiichi Umetsu, Mario Nonino +35
The galaxy cluster MACS J0717.5+3745 (z=0.55) is the largest known cosmic lens, with complex internal structures seen in deep X-ray, Sunyaev-Zel'dovich effect and dynamical observa…
CLASH-X: A Comparison of Lensing and X-ray Techniques for Measuring the Mass Profiles of Galaxy Clusters
Megan Donahue, G. Mark Voit, Andisheh Mahdavi +35
We present profiles of temperature (Tx), gas mass, and hydrostatic mass estimated from new and archival X-ray observations of CLASH clusters. We compare measurements derived from X…
A Brightest Cluster Galaxy with an Extremely Large Flat Core
Marc Postman, Tod R. Lauer, Megan Donahue +14
Hubble Space Telescope images of the galaxy cluster Abell 2261, obtained as part of the Cluster Lensing And Supernova survey with Hubble, show that the brightest galaxy in the clus…
CLASH: Mass Distribution in and around MACS J1206.2-0847 from a Full Cluster Lensing Analysis
Keiichi Umetsu, Elinor Medezinski, Mario Nonino +45
We derive an accurate mass distribution of the galaxy cluster MACS J1206.2-0847 (z=0.439) from a combined weak-lensing distortion, magnification, and strong-lensing analysis of wid…
Formation and Evolution of E and S0 Galaxies from HST and Keck Studies of z~0.3-1 Clusters
Garth Illingworth, Daniel Kelson, Pieter van Dokkum +1
We have witnessed a dramatic increase over the last five years in results on distant galaxies, in large part because of the high resolution imaging capability of HST, and the multi…
A sample of short-lived Galactic radio transients from ASKAP VAST
Akash Anumarlapudi, David L. Kaplan, Natasha Hurley Walker +6
Galactic radio transients (GRTs) are mysterious short-lived (~days to months) radio transients that are quiet at all other wavelengths. Until now, roughly half a dozen such sources…
A fast powerful X-ray transient from possible tidal disruption of a white dwarf
Dongyue Li, Wenda Zhang, Jun Yang +97
Stars captured by black holes (BHs) can be torn apart by strong tidal forces, producing electromagnetic flares. To date, more than 100 tidal disruption events (TDEs) have been obse…
