Slicing the cool circumgalactic medium along the major-axis of a star-forming galaxy at
S. Lopez, N. Tejos, L. F. Barrientos +13
We present spatially-resolved echelle spectroscopy of an intervening MgII-FeII-MgI absorption-line system detected at toward the giant gravitational arc PSZ1…
Strong Lensing Model of SPT-CLJ0356-5337, a Major Merger Candidate at Redshift 1.0359
Guillaume Mahler, Keren Sharon, Michael D. Gladders +10
We present an analysis of the mass distribution inferred from strong lensing by SPT-CL J0356-5337, a cluster of galaxies at redshift z = 1.0359 revealed in the follow-up of the SPT…
An X-ray Detection of Star Formation In a Highly Magnified Giant Arc
M. B. Bayliss, M. McDonald, K. Sharon +19
In the past decade, our understanding of how stars and galaxies formed during the first 5 billion years after the Big Bang has been revolutionized by observations that leverage gra…
The SPTpol Extended Cluster Survey
L. E. Bleem, S. Bocquet, B. Stalder +135
We describe the observations and resultant galaxy cluster catalog from the 2770 deg SPTpol Extended Cluster Survey (SPT-ECS). Clusters are identified via the Sunyaev-Zel'dovich…
Galaxy Clusters Selected via the Sunyaev-Zel'dovich Effect in the SPTpol 100-Square-Degree Survey
N. Huang, L. E. Bleem, B. Stalder +74
We present a catalog of galaxy cluster candidates detected in 100 square degrees surveyed with the SPTpol receiver on the South Pole Telescope. The catalog contains 89 candidates d…
The production and escape of ionizing photons from galaxies over cosmic time (Astro2020 Science White Paper)
Jane R. Rigby, Danielle Berg, Rongmon Bordoloi +10
The ionizing photons produced by massive stars are key actors in galaxy evolution. Ionizing photon production and escape is poorly understood. Improved space-based, spatially-resol…
Constraining the metallicities, ages, star formation histories, and ionizing continua of extragalactic massive star populations
J. Chisholm, J. R. Rigby, M. Bayliss +4
We infer the properties of massive star populations using the far-ultraviolet stellar continua of 61 star-forming galaxies: 42 at low-z observed with HST and 19 at z~2 from the Meg…
Anatomy of a Cooling Flow: The Feedback Response to Pure Cooling in the Core of the Phoenix Cluster
M. McDonald, B. R. McNamara, G. M. Voit +17
We present new, deep observations of the Phoenix cluster from the Chandra X-ray Observatory, the Hubble Space Telescope, and the Karl Jansky Very Large Array. These data provide an…
Strong Lens Models for 37 Clusters of Galaxies from the SDSS Giant Arcs Survey
Keren Sharon, Matthew B. Bayliss, Håkon Dahle +12
We present strong gravitational lensing models for 37 galaxy clusters from the SDSS Giant Arcs Survey. We combine data from multi-band Hubble Space Telescope WFC3imaging, with grou…
Gravitational lensing reveals ionizing ultraviolet photons escaping from a distant galaxy
T. Emil Rivera-Thorsen, Håkon Dahle, John Chisholm +7
During the epoch of reionisation, neutral gas in the early Universe was ionized by hard ultraviolet radiation emitted by young stars in the first galaxies. To do so, ionizing ultra…
Spatially Resolved Outflows in a Seyfert Galaxy at z = 2.39
Travis C. Fischer, J. R. Rigby, G. Mahler +11
We present the first spatially resolved analysis of rest-frame optical and UV imaging and spectroscopy for a lensed galaxy at z = 2.39 hosting a Seyfert active galactic nucleus (AG…
Lens Model and Source Reconstruction Reveal the Morphology and Star Formation Distribution in the Cool Spiral LIRG SGAS J143845.1145407
Samuel J. Dunham, Keren Sharon, Michael K. Florian +8
We present () imaging and grism spectroscopy of a strongly lensed LIRG at , SGAS 143845.1145407, and use the magnification boost of grav…
