Casey Papovich,Ivelina Momcheva,Christopher N. A. Willmer,Keely D. Finkelstein,Steven L. Finkelstein,Kim-Vy Tran,Mark Brodwin,James Dunlop,Duncan Farrah,S. A. Khan,S. A. Khan,Jennifer M. Lotz,Patrick J. McCarthy,Ross J. McLure,Marcia J. Rieke,Gregory Rudnick,Suresh Sivanandam,Florian Pacaud,Marguerite Pierre +18 more
TL;DR: In this paper, the authors reported the discovery of a galaxy cluster at z = 1.62 located in the Spitzer Wide Area Infrared Extragalactic survey XMM-LSS field.
Journal ArticleDOI
Galaxy cluster baryon fractions revisited
TL;DR: In this article, the authors measured the baryons contained in both the stellar and hot-gas components for 12 galaxy clusters and groups at z ~ 0.1 with M = 1-5? 1014 M?.
Journal ArticleDOI
Thermal infrared mmtao observations of the hr 8799 planetary system
Philip M. Hinz,Timothy J. Rodigas,Matthew A. Kenworthy,Suresh Sivanandam,Aren Heinze,Eric E. Mamajek,Michael R. Meyer,Michael R. Meyer +7 more
TL;DR: In this article, direct imaging observations at wavelengths of 3.3, 3.8, and 4.8 (M band) μm are presented for the planetary system surrounding HR-8799.
Journal ArticleDOI
First On-Sky High-Contrast Imaging with an Apodizing Phase Plate*
Matthew A. Kenworthy,Johanan L. Codona,Philip M. Hinz,J. Roger P. Angel,A. N. Heinze,Suresh Sivanandam +5 more
TL;DR: In this paper, the authors presented the first astronomical observations obtained with an apodizing phase plate (APP), which was designed to suppress the stellar diffraction pattern by 5 mag from 2 - 9λ/D over a 180° region.
Journal ArticleDOI
Enrichment and pre-heating in intragroup gas from galactic outflows
TL;DR: In this paper, the authors examined metal and entropy content in galaxy groups having T x ≈ 0.5-2 keV in cosmological hydrodynamic simulations, including a well-constrained prescription for galactic outflows following momentum-driven wind scalings and a sophisticated chemical evolution model.
