Journal ArticleDOI
Cosmic evolution of virial and stellar mass in massive early-type galaxies*
David J. Lagattuta,Christopher D. Fassnacht,Matthew W. Auger,Matthew W. Auger,Philip J. Marshall,Marusa Bradac,Tommaso Treu,Raphael Gavazzi,Tim Schrabback,C. Faure,Timo Anguita +10 more
TL;DR: In this paper, the average mass properties of a sample of 41 strong and weak gravitational lenses at moderate redshift (z similar to 0.4-0.9) were measured and the lens redshift for six of these galaxies for the first time.
Journal ArticleDOI
Spitzer UltRa Faint SUrvey Program (SURFS UP). II. IRAC-detected Lyman-Break Galaxies at 6 ≲ z ≲ 10 behind Strong-lensing Clusters
Kuang-Han Huang,Marusa Bradac,Brian C. Lemaux,R. E. Ryan,Austin Hoag,Marco Castellano,Ricardo Amorín,Adriano Fontana,Gabriel B. Brammer,Benjamin Cain,L. M. Lubin,Emiliano Merlin,Kasper B. Schmidt,Tim Schrabback,Tommaso Treu,Anthony H. Gonzalez,Anja von der Linden,Anja von der Linden,Robert I. Knight +18 more
TL;DR: In this article, the stellar population properties of the IRAC-detected $6 \lesssim z − 10$ galaxy candidates from the Spitzer UltRa Faint SUrvey Program (SURFS UP) were studied.
Journal ArticleDOI
The grism lens-amplified survey from space (glass). iv. mass reconstruction of the lensing cluster abell 2744 from frontier field imaging and glass spectroscopy
Xin Wang,Austin Hoag,Kuang-Han Huang,Tommaso Treu,Marusa Bradac,Kasper B. Schmidt,Gabriel B. Brammer,Benedetta Vulcani,T. A. Jones,Russell E. Ryan,Ricardo Amorín,Marco Castellano,Adriano Fontana,E. Merlin,Michele Trenti +14 more
TL;DR: Wang et al. as discussed by the authors presented a strong and weak lensing reconstruction of the massive cluster Abell 2744, the first cluster for which deep Hubble Frontier Fields (HFF) images and spectroscopy from the Grism Lens-Amplified Survey from Space (GLASS) are available.
Journal ArticleDOI
EARLY-TYPE GALAXIES AT z ∼ 1.3. III. ON THE DEPENDENCE OF FORMATION EPOCHS AND STAR FORMATION HISTORIES ON STELLAR MASS AND ENVIRONMENT

Ellis,Fumiaki Nakata,Mario Nonino,Tommaso Treu,John P. Blakeslee,Ricardo Demarco,Peter Eisenhardt,Holland C. Ford,R. A. E. Fosbury,Garth D. Illingworth,Marc Huertas-Company,Myungkook J. Jee,Tadayuki Kodama,Marc Postman,Masayuki Tanaka,Richard L. White +25 more
TL;DR: In this article, the authors study the environmental dependence of stellar population properties at z = 1.3 and find that, approximately 1 Gyr after the onset of star formation, the majority (75%) of cluster galaxies have already assembled most (>80%) of their final mass, while, by the same time, fewer field ETGs have.
Journal ArticleDOI
Spitzer ultra faint survey program (surfs up). i. an overview
Marusa Bradac,Russell E. Ryan,Stefano Casertano,Kuang-Han Huang,Brian C. Lemaux,Tim Schrabback,Anthony H. Gonzalez,Steve Allen,Benjamin Cain,Michael D. Gladders,Nicholas Hall,Hendrik Hildebrandt,Joannah L. Hinz,Anja von der Linden,Anja von der Linden,Lori M. Lubin,Tommaso Treu,Dennis Zaritsky +17 more
TL;DR: SURFS UP as mentioned in this paper is a joint Spitzer and HST Exploration Science program using 10 galaxy clusters as cosmic telescopes to study z & 7 galaxies at intrinsically lower luminosities, enabled by gravitational lensing, than blank field surveys of the same exposure time.
