Modeling X-ray binary evolution in normal galaxies: Insights from SINGS
P. Tzanavaris, T. Fragos, M. Tremmel +7
We present the largest-scale comparison to date between observed extragalactic X-ray binary (XRB) populations and theoretical models of their production. We construct observational…
Evidence for Elevated X-ray Emission in Local Lyman Break Galaxy Analogs
Antara R. Basu-Zych, Bret D. Lehmer, Ann E. Hornschemeier +6
In this paper, we study the relationship between the 2-10 keV X-ray luminosity (L_X), assumed to originate from X-ray binaries (XRBs), and star formation rate (SFR) in UV-selected…
Energy Feedback from X-ray Binaries in the Early Universe
Tassos Fragos, Bret D. Lehmer, Smadar Naoz +2
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 inter-galactic me…
The X-ray Star Formation Story as Told by Lyman Break Galaxies in the 4 Ms CDF-S
Antara R. Basu-Zych, Bret D. Lehmer, Ann E. Hornschemeier +12
We present results from deep X-ray stacking of >4000 high redshift galaxies from z~1 to 8 using the 4 Ms Chandra Deep Field South (CDF-S) data, the deepest X-ray survey of the extr…
Modeling the Redshift Evolution of the Normal Galaxy X-ray Luminosity Function
M. Tremmel, T. Fragos, B. D. Lehmer +9
Emission from X-ray binaries (XRBs) is a major component of the total X-ray luminosity of normal galaxies, so X-ray studies of high redshift galaxies allow us to probe the formatio…
A search for AGN in the most extreme UV-selected starbursts using the European VLBI Network
R. Alexandroff, R. A. Overzier, Z. Paragi +7
We have used the European VLBI Network (EVN) to observe a sample of Lyman Break Analogs (LBAs), nearby (z < 0.3) galaxies with properties similar to the more distant Lyman Break Ga…
A Search for Lyman Break Galaxies in the CDF-S Using Swift UVOT
Antara R. Basu-Zych, Ann E. Hornschemeier, Erik A. Hoversten +2
(Abridged) While the Swift satellite is primarily designed to study gamma-ray bursts, its ultraviolet and optical imaging and spectroscopy capabilities are also being used for a va…
The Chandra Deep Field-South Survey: 4 Ms Source Catalogs
Y. Q. Xue, B. Luo, W. N. Brandt +22
[abridged] We present point-source catalogs for the 4Ms Chandra Deep Field-South (CDF-S), which is the deepest Chandra survey to date and covers an area of 464.5 arcmin^2. We provi…
Lyman Break Analogs: Constraints on the Formation of Extreme Starbursts at Low and High Redshift
Thiago S. Gonçalves, Roderik Overzier, Antara Basu-Zych +1
Lyman Break Analogs (LBAs), characterized by high far-UV luminosities and surface brightnesses as detected by GALEX, are intensely star-forming galaxies in the low-redshift univers…
Extreme Feedback and the Epoch of Reionization: Clues in the Local Universe
Timothy M. Heckman, Sanchayeeta Borthakur, Roderik Overzier +8
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 wh…
Dust Attenuation in UV-selected Starbursts at High Redshift and their Local Counterparts: Implications for the Cosmic Star Formation Rate Density
Roderik Overzier, Tim Heckman, Jing Wang +14
We present a new analysis of the dust obscuration in starburst galaxies at low and high redshift. This study is motivated by our unique sample of the most extreme UV-selected starb…
The kinematics of ionized gas in Lyman-Break Analogs at z ~ 0.2
Thiago S. Gonçalves, Antara Basu-Zych, Roderik Overzier +7
We present results for 19 "Lyman Break Analogs" (LBAs) observed with Keck/OSIRIS with an AO-assisted spatial resolution of less than 200 pc. We detect satellites/companions, diffus…
The GALEX Arecibo SDSS Survey II: The Star Formation Efficiency of Massive Galaxies
David Schiminovich, Barbara Catinella, Guinevere Kauffmann +23
We use measurements of the HI content, stellar mass and star formation rates in ~190 massive galaxies with stellar masses greater than 10^10 Msun, obtained from the Galex Arecibo S…
The GALEX Arecibo SDSS Survey. I. Gas Fraction Scaling Relations of Massive Galaxies and First Data Release
Barbara Catinella, David Schiminovich, Guinevere Kauffmann +23
We introduce the GALEX Arecibo SDSS Survey (GASS), an on-going large program that is gathering high quality HI-line spectra using the Arecibo radio telescope for an unbiased sample…
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. A. Overzier, T. M. Heckman, C. Tremonti +10
We present HST UV/optical imaging, Spitzer mid-IR photometry, and optical spectroscopy of a sample of 30 low-redshift (z=0.1-0.3) galaxies chosen from SDSS/GALEX to be accurate loc…
