TL;DR: Using a mid-infrared calibration of the Cepheid distance scale based on recent observations at 3.6μm with the Spitzer Space Telescope, a new, high-accuracy calibration was obtained by as mentioned in this paper, which decreased the systematic uncertainty in H 0 over that obtained by the Hubble Space Telescope Key Project by over a factor of three.

TL;DR: In this paper, the authors used observations from the FourStar Galaxy Evolution Survey (ZFOURGE) to obtain the deepest measurements to date of the galaxy stellar mass function (SMF) at 0.2 < z < 3.5.

TL;DR: In this paper, the authors explore star formation histories (SFHs) of galaxies based on the evolution of the star formation rate stellar mass relation (SFR-M*), using data from the FourStar Galaxy Evolution Survey (ZFOURGE) in combination with far-IR imaging from the Spitzer and Herschel observatories.

TL;DR: In this paper, the authors reported the likely identification of a substantial population of massive M ~ 1011 M ☉ galaxies at z = 4 with suppressed star formation rates (SFRs), selected on rest-frame optical to near-IR colors from the FourStar Galaxy Evolution Survey (ZFOURGE).

TL;DR: In this article, the authors present observations of the afterglows and host galaxies of three short-duration gamma-ray bursts (GRBs): 100625A, 101219A and 110112A. The bursts have inferred circumburst densities of ~1e-4-1 cm^-3, and isotropic-equivalent gamma energy and kinetic energies of 1e50-1e51 erg.
