The Dynamical Mass and Three-Dimensional Orbit of HR7672B: A Benchmark Brown Dwarf with High Eccentricity
Justin R. Crepp, John Asher Johnson, Debra A. Fischer +10
The companion to the G0V star HR7672 directly imaged by Liu et al. (2002) has moved measurably along its orbit since the discovery epoch, making it possible to determine its dynami…
Early radio and X-ray observations of the youngest nearby type Ia supernova PTF11kly (SN 2011fe)
Assaf Horesh, S. R. Kulkarni, Derek B. Fox +20
On August 24 (UT) the Palomar Transient Factory (PTF) discovered PTF11kly (SN 2011fe), the youngest and most nearby type Ia supernova (SN Ia) in decades. We followed this event up…
Multi-wavelength modeling of the spatially resolved debris disk of HD 107146
Steve Ertel, Sebastian Wolf, Stanimir Metchev +5
(abridged) We aim to constrain the location, composition, and dynamical state of planetesimal populations and dust around the young, sun-like (G2V) star HD 107146}. We consider cor…
The Birth of a Relativistic Outflow in the Unusual γ-ray Transient Swift J164449.3+573451
B. A. Zauderer, E. Berger, A. M. Soderberg +24
Active galactic nuclei (AGN), powered by long-term accretion onto central supermassive black holes, produce relativistic jets with lifetimes of greater than one million yr that pre…
Physical conditions of the interstellar medium of high-redshift, strongly lensed submillimetre galaxies from the Herschel-ATLAS
Ivan Valtchanov, J. Virdee, R. J. Ivison +51
We present Herschel-SPIRE Fourier Transform Spectrometer (FTS) and radio follow-up observations of two Herschel-ATLAS (H-ATLAS) detected strongly lensed distant galaxies. In one of…
Dynamical Structure of the Molecular Interstellar Medium in an Extremely Bright, Multiply Lensed z~3 Submillimeter Galaxy Discovered with Herschel
Dominik A. Riechers, A. Cooray, A. Omont +51
We report the detection of CO 5-4, 3-2, and 1-0 emission in the strongly lensed, Herschel/SPIRE-selected submillimeter galaxy (SMG) HLSW-01 at z=2.9574+/-0.0001, using the Plateau…
