The GALEX Arecibo SDSS Survey I: gas fraction scaling relations of massive galaxies and first data release
- B. Catinella, D. Schiminovich, T. Wyder
- Physics
- 9 December 2009
We introduce the GALEX Arecibo SDSS Survey (GASS), an on-going large programme that is gathering high quality H i-line spectra using the Arecibo radio telescope for an unbiased sample of ~1000…
The Coincidence of Nuclear Star Clusters and Active Galactic Nuclei
- A. Seth, M. Agüeros, Duane M. Lee, A. Basu-Zych
- Physics
- 2 January 2008
We study galaxies that host both nuclear star clusters and AGNs, implying the presence of a massive black hole. We select a sample of 176 galaxies with previously detected nuclear star clusters that…
EXTREME FEEDBACK AND THE EPOCH OF REIONIZATION: CLUES IN THE LOCAL UNIVERSE
- T. Heckman, S. Borthakur, M. Seibert
- Physics
- 21 January 2011
The source responsible for reionizing the universe at z>6 remains uncertain. While an energetically adequate population of star-forming galaxies may be in place, it is unknown whether a large enough…
ENERGY FEEDBACK FROM X-RAY BINARIES IN THE EARLY UNIVERSE
- T. Fragos, B. Lehmer, S. Naoz, A. Zezas, A. Basu-Zych
- Physics
- 6 June 2013
X-ray photons, because of their long mean-free paths, can easily escape the galactic environments where they are produced, and interact at long distances with the intergalactic medium, potentially…
LOCAL LYMAN BREAK GALAXY ANALOGS: THE IMPACT OF MASSIVE STAR-FORMING CLUMPS ON THE INTERSTELLAR MEDIUM AND THE GLOBAL STRUCTURE OF YOUNG, FORMING GALAXIES
- R. Overzier, T. Heckman, M. Seibert
- Physics
- 7 October 2009
We report on the results of Hubble Space Telescope optical and UV imaging, Spitzer mid-IR photometry, and optical spectroscopy of a sample of 30 low-redshift (z ∼ 0.1 to 0.3) galaxies chosen from the…
X-RAY BINARY EVOLUTION ACROSS COSMIC TIME
High-redshift galaxies permit the study of the formation and evolution of X-ray binary (XRB) populations on cosmological timescales, probing a wide range of metallicities and star formation rates…
DUST ATTENUATION IN UV-SELECTED STARBURSTS AT HIGH REDSHIFT AND THEIR LOCAL COUNTERPARTS: IMPLICATIONS FOR THE COSMIC STAR FORMATION RATE DENSITY
- R. Overzier, T. Heckman, D. Schiminovich
- Physics
- 28 November 2010
We present a new analysis of the dust obscuration in starburst galaxies at low and high redshifts. This study is motivated by our unique sample of the most extreme UV-selected starburst galaxies in…
THE KINEMATICS OF IONIZED GAS IN LYMAN-BREAK ANALOGS AT z ∼ 0.2
- T. Gonçalves, A. Basu-Zych, T. Heckman
- Physics
- 24 September 2010
We present results for 19 “Lyman-break analogs” observed with Keck/OSIRIS with an adaptive-optics-assisted spatial resolution of less than 200 pc. We detect satellites/companions, diffuse emission,…
THE CHANDRA DEEP PROTOCLUSTER SURVEY: Lyα BLOBS ARE POWERED BY HEATING, NOT COOLING
- J. Geach, D. Alexander, A. Basu-Zych
- Physics
- 3 April 2009
We present the results of a 400 ks Chandra survey of 29 extended Lyα emitting nebulae (Lyα Blobs, LABs) in the z = 3.09 protocluster in the SS A22 field. We detect luminous X-ray counterparts in five…
Hubble Space Telescope Morphologies of Local Lyman Break Galaxy Analogs. I. Evidence for Starbursts Triggered by Merging
- R. Overzier, T. Heckman, B. Madore
- Physics
- 20 September 2007
Heckman and coworkers used the GALEX UV imaging survey to show that there exists a rare population of nearby compact UV-luminous galaxies (UVLGs) that closely resemble high-redshift Lyman break…
