BUCS: An Engine For Generating Realistic Imaging Data for Deep Galaxy Fields
Rychard J. Bouwens, Garth D. Illingworth, Daniel Magee
Today's deep high resolution multiwavelength surveys contain a wealth of information about galaxies at different epochs. To fully exploit this information, it is useful to be able…
An Hα view of galaxy build-up in the first 2 Gyr: luminosity functions at z~4-6.5 from NIRCam/grism spectroscopy
Alba Covelo-Paz, Emma Giovinazzo, Pascal A. Oesch +22
The Hα nebular emission line is an optimal tracer for recent star formation in galaxies. With the advent of JWST, this line has recently become observable at z>3 for the first tim…
3D-HST WFC3-selected Photometric Catalogs in the Five CANDELS/3D-HST Fields: Photometry, Photometric Redshifts and Stellar Masses
Rosalind E. Skelton, Katherine E. Whitaker, Ivelina G. Momcheva +24
The 3D-HST and CANDELS programs have provided WFC3 and ACS spectroscopy and photometry over ~900 square arcminutes in five fields: AEGIS, COSMOS, GOODS-North, GOODS-South, and the…
Discovery of Two Distant Type Ia Supernovae in the Hubble Deep Field North with the Advanced Camera for Surveys
John P. Blakeslee, Zlatan I. Tsvetanov, Adam G. Riess +30
We present observations of the first two supernovae discovered with the recently installed Advanced Camera for Surveys (ACS) on the Hubble Space Telescope. The supernovae were foun…
Field E+A Galaxies at Intermediate Redshifts (0.3<z<1)
Kim-Vy H. Tran, Marijn Franx, Garth D. Illingworth +3
We select E+A candidates from a spectroscopic dataset of ~800 field galaxies and measure the E+A fraction at 0.3<z<1 to be 2.7+/-1.1%, a value lower than that in galaxy clusters at…
The 3D-HST Survey: Hubble Space Telescope WFC3/G141 grism spectra, redshifts, and emission line measurements for galaxies
Ivelina G. Momcheva, Gabriel B. Brammer, Pieter G. van Dokkum +27
We present reduced data and data products from the 3D-HST survey, a 248-orbit HST Treasury program. The survey obtained WFC3 G141 grism spectroscopy in four of the five CANDELS fie…
Accelerated quenching and chemical enhancement of massive galaxies in a gas-rich halo
Pablo G. Pérez-González, Francesco D`Eugenio, Bruno RodrÃguez del Pino +18
Stars in galaxies form when baryons radiatively cool down and fall into gravitational wells whose mass is dominated by dark matter. Eventually, star formation quenches as gas is de…
The Hubble Legacy Fields (HLF-GOODS-S) v1.5 Data Products: Combining 2442 Orbits of GOODS-S/CDF-S Region ACS and WFC3/IR Images
Garth Illingworth, Daniel Magee, Rychard Bouwens +7
We have submitted to MAST the 1.5 version data release of the Hubble Legacy Fields (HLF) project covering a 25 x 25 arcmin area over the GOODS-S (ECDF-S) region from the HST archiv…
Confirmation of the remarkable compactness of massive quiescent galaxies at z~2.3: early-type galaxies did not form in a simple monolithic collapse
Pieter van Dokkum, Marijn Franx, Mariska Kriek +9
Using deep near-infrared spectroscopy Kriek et al. (2006) found that ~45% of massive galaxies at z~2.3 have evolved stellar populations and little or no ongoing star formation. Her…
The Hubble Legacy Field GOODS-S Photometric Catalog
Katherine E. Whitaker, Mohammad Ashas, Garth Illingworth +12
This manuscript describes the public release of the Hubble Legacy Fields (HLF) project photometric catalog for the extended GOODS-South region from the Hubble Space Telescope (HST)…
The Velocity Dispersion of MS1054-03: A Massive Galaxy Cluster at High Redshift
Kim-Vy H. Tran, Daniel D. Kelson, Pieter van Dokkum +3
We present results from a dynamical study of the high redshift, massive, X-ray luminous galaxy cluster MS1054--03. We significantly increase the number of confirmed cluster members…
Tracing the Mass Growth and Star Formation Rate Evolution of Massive Galaxies from z~6 to z~1 in the Hubble Ultra-Deep Field
Britt F. Lundgren, Pieter van Dokkum, Marijn Franx +8
We present an analysis of 1500 H160-selected photometric galaxies detected to a limiting magnitude of 27.8 in the HUDF, using imaging from the HST WFC3/IR camera in combinati…
Deciphering Lyman- Emission Deep into the Epoch of Reionisation
Callum Witten, Nicolas Laporte, Sergio Martin-Alvarez +18
During the epoch of reionisation the first galaxies were enshrouded in pristine neutral gas, with one of the brightest emission lines in star-forming galaxies, Lyman- (Ly),…
Observations of environmental quenching in groups in the 11 Gyr since z=2.5: different quenching for central and satellite galaxies
Tomer Tal, Avishai Dekel, Pascal Oesch +16
We present direct observational evidence for star formation quenching in galaxy groups in the redshift range 0<z<2.5. We utilize a large sample of nearly 6000 groups, selected by f…
An initial investigation of the performance of GPU-based swept time-space decomposition
Daniel Magee, Kyle E Niemeyer
Simulations of physical phenomena are essential to the expedient design of precision components in aerospace and other high-tech industries. These phenomena are often described by…
Accelerated Formation of Ultra-Massive Galaxies in the First Billion Years
Mengyuan Xiao, Pascal Oesch, David Elbaz +35
Recent JWST observations have revealed an unexpected abundance of massive galaxy candidates in the early Universe, extending further in redshift and to lower luminosity than what h…
