MAGIC: Muse gAlaxy Groups In Cosmos -- A survey to probe the impact of environment on galaxy evolution over the last 8 Gyr
B. Epinat, T. Contini, W. Mercier +22
We introduce the MUSE gAlaxy Groups in COSMOS (MAGIC) survey, which was built to study the impact of environment on galaxy evolution over the last 8 Gyr. It consists of 17 MUSE fie…
An high definition view of the COSMOS Wall at z~0.73
A. Iovino, V. Petropoulou, M. Scodeggio +14
We present a study of a large filamentary structure at z~0.73 in the field of the COSMOS survey, the so-called COSMOS Wall. This structure encompasses a comprehensive range of envi…
Large scale structure around a z=2.1 cluster
Chao-Ling Hung, Caitlin M. Casey, Yi-Kuan Chiang +10
The most prodigious starburst galaxies are absent in massive galaxy clusters today, but their connection with large scale environments is less clear at . We present a se…
Discovery of Massive, Mostly Star-formation Quenched Galaxies with Extremely Large Lyman-alpha Equivalent Widths at z ~ 3
Yoshiaki Taniguchi, Masaru Kajisawa, Masakazu A. R. Kobayashi +21
We report a discovery of 6 massive galaxies with both extremely large Lya equivalent width and evolved stellar population at z ~ 3. These MAssive Extremely STrong Lya emitting Obje…
A massive, distant proto-cluster at z=2.47 caught in a phase of rapid formation?
C. M. Casey, A. Cooray, P. Capak +6
Numerical simulations of cosmological structure formation show that the Universe's most massive clusters, and the galaxies living in those clusters, assemble rapidly at early times…
Correlating galaxy colour and halo concentration: A tunable Halo Model of galactic conformity
Aseem Paranjape, Katarina Kovac, William G. Hartley +1
We extend the Halo Occupation Distribution (HOD) framework to generate mock galaxy catalogs exhibiting varying levels of "galactic conformity", which has emerged as a potentially p…
Combined CO & Dust Scaling Relations of Depletion Time and Molecular Gas Fractions with Cosmic Time, Specific Star Formation Rate and Stellar Mass
R. Genzel, L. J. Tacconi, D. Lutz +33
We combine molecular gas masses inferred from CO emission in 500 star forming galaxies (SFGs) between z=0 and 3, from the IRAM-COLDGASS, PHIBSS1/2 and other surveys, with gas masse…
The FMOS-COSMOS survey of star-forming galaxies at z~1.6 III. Survey design, performance, and sample characteristics
J. D. Silverman, D. Kashino, D. Sanders +27
We present a spectroscopic survey of galaxies in the COSMOS field using the Fiber Multi-Object Spectrograph (FMOS), a near-infrared instrument on the Subaru Telescope. Our survey i…
Quenching of Star Formation in SDSS Groups: Centrals, Satellites, and Galactic Conformity
Christian Knobel, Simon J. Lilly, Joanna Woo +1
We re-examine the fraction of low-redshift Sloan Digital Sky Survey satellites and centrals in which star formation has been quenched, using the environment quenching efficiency fo…
Evolution of the Most Massive Galaxies to z=0.6: I. A New Method for Physical Parameter Estimation
Yan-Mei Chen, Guinevere Kauffmann, Christy A. Tremonti +10
We use principal component analysis (PCA) to estimate stellar masses, mean stellar ages, star formation histories (SFHs), dust extinctions and stellar velocity dispersions for ~290…
zCOSMOS 10k-bright spectroscopic sample: exploring mass and environment dependence in early-type galaxies
M. Moresco, L. Pozzetti, A. Cimatti +58
We present the analysis of the U-V rest-frame color distribution and some spectral features as a function of mass and environment for two sample of early-type galaxies up to z=1 ex…
The Dependence of Star Formation Activity on Stellar Mass Surface Density and Sersic Index in zCOSMOS Galaxies at 0.5<z<0.9 Compared with SDSS Galaxies at 0.04<z<0.08
C. Maier, S. J. Lilly, G. Zamorani +56
One of the key unanswered questions in the study of galaxy evolution is what physical processes inside galaxies drive the changes in the SFRs in individual galaxies that, taken tog…
