Deconstructing the galaxy stellar mass function with UKIDSS and CANDELS: the impact of colour, structure and environment
Fontana, Adriano; Grogin, Norman A.; Kocevski, Dale D. +15 more
We combine photometry from the Ultra Deep Survey (UDS), Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) UDS and CANDELS the Great Observatories Origins Deep Survey-South (GOODS-S) surveys to construct the galaxy stellar mass function probing both the low- and high-mass end accurately in the redshift range 0.3 < z < 3…
The truncated and evolving inner accretion disc of the black hole GX 339-4
Ponti, G.; Fender, R. P.; Muñoz-Darias, T. +2 more
The nature of accretion onto stellar mass black holes in the low/hard state remains unresolved, with some evidence suggesting that the inner accretion disc is truncated and replaced by a hot flow. However, the detection of relativistic broadened Fe emission lines, even at relatively low luminosities, seems to require an accretion disc extending fu…
The Star Formation Histories of Local Group Dwarf Galaxies. III. Characterizing Quenching in Low-mass Galaxies
Dolphin, Andrew E.; Skillman, Evan D.; Williams, Benjamin F. +4 more
We explore the quenching of low-mass galaxies (104 ≲ {{M}\star } ≲ 108 {{M}⊙ }) as a function of lookback time using the star formation histories (SFHs) of 38 Local Group dwarf galaxies. The SFHs were derived by analyzing color-magnitude diagrams of resolved stellar populations in archival Hubble Space T…
Velocity-resolved [CII] Emission and [CII]/FIR Mapping along Orion with Herschel
Falgarone, E.; Teyssier, D.; Ossenkopf, V. +22 more
We present the first ∼7.‧5 × 11.‧5 velocity-resolved (∼0.2 km s-1) map of the [C ii] 158 µm line toward the Orion molecular cloud 1 (OMC 1) taken with the Herschel/HIFI instrument. In combination with far-IR (FIR) photometric images and velocity-resolved maps of the H41α hydrogen recombination and CO J = 2-1 lines, this data set p…
Hops 383: an Outbursting Class 0 Protostar in Orion
Fischer, William J.; Wilson, T. L.; Watson, Dan M. +11 more
We report the dramatic mid-infrared brightening between 2004 and 2006 of Herschel Orion Protostar Survey (HOPS) 383, a deeply embedded protostar adjacent to NGC 1977 in Orion. By 2008, the source became a factor of 35 brighter at 24 µm with a brightness increase also apparent at 4.5 µm. The outburst is also detected in the submillimete…
Extreme emission-line galaxies out to z ~ 1 in zCOSMOS. I. Sample and characterization of global properties
Kneib, J. -P.; Silverman, J. D.; Bolzonella, M. +37 more
Context. The study of large and representative samples of low-metallicity star-forming galaxies at different cosmic epochs is of great interest to the detailed understanding of the assembly history and evolution of low-mass galaxies.
Aims: We present a thorough characterization of a large sample of 183 extreme emission-line galaxies (EELGs) a…
Far-infrared Dust Temperatures and Column Densities of the MALT90 Molecular Clump Sample
Hoq, Sadia; Jackson, James M.; Sanhueza, Patricio +4 more
We present dust column densities and dust temperatures for ∼3000 young, high-mass molecular clumps from the Millimeter Astronomy Legacy Team 90 GHz survey, derived from adjusting single-temperature dust emission models to the far-infrared intensity maps measured between 160 and 870 µm from the Herschel/Herschel Infrared Galactic Plane Survey…
POLARBEAR constraints on cosmic birefringence and primordial magnetic fields
Chapman, Scott; Sherwin, Blake D.; Errard, Josquin +84 more
We constrain anisotropic cosmic birefringence using four-point correlations of even-parity E -mode and odd-parity B -mode polarization in the cosmic microwave background measurements made by the POLARization of the Background Radiation (POLARBEAR) experiment in its first season of observations. We find that the anisotropic cosmic birefringence sig…
OSIRIS observations of meter-sized exposures of H2O ice at the surface of 67P/Churyumov-Gerasimenko and interpretation using laboratory experiments
Jorda, L.; Lamy, P. L.; Bertaux, J. -L. +52 more
Since OSIRIS started acquiring high-resolution observations of the surface of the nucleus of comet 67P/Churyumov-Gerasimenko, over one hundred meter-sized bright spots have been identified in numerous types of geomorphologic regions, but mostly located in areas receiving low insolation. The bright spots are either clustered, in debris fields close…
Zooming In on the Progenitors of Superluminous Supernovae With the HST
Berger, E.; Kirshner, R. P.; Rest, A. +25 more
We present Hubble Space Telescope (HST) rest-frame ultraviolet imaging of the host galaxies of 16 hydrogen-poor superluminous supernovae (SLSNe), including 11 events from the Pan-STARRS Medium Deep Survey. Taking advantage of the superb angular resolution of HST, we characterize the galaxies’ morphological properties, sizes, and star formation rat…
