Fast single-dish scans of the Sun using ALMA

Kavli Affiliate: Richard Hills | First 5 Authors: Neil Phillips, Richard Hills, Tim Bastian, Hugh Hudson, Ralph Marson | Summary: We have implemented control and data-taking software that makes it possible to scan the beams of individual ALMA antennas to perform quite complex patterns while recording the signals at high rates. We conducted test observations […]

Strong Lens Time Delay Challenge: II. Results of TDC1

Kavli Affiliate: Kaisey Mandel | First 5 Authors: Kai Liao, Tommaso Treu, Phil Marshall, Christopher D. Fassnacht, Nick Rumbaugh | Summary: We present the results of the first strong lens time delay challenge. The motivation, experimental design, and entry level challenge are described in a companion paper. This paper presents the main challenge, TDC1, which […]

No excess of bright galaxies around the redshift 7.1 quasar ULAS J1120+0641

Kavli Affiliate: R. G. McMahon | First 5 Authors: Chris Simpson, Daniel Mortlock, Stephen Warren, Sebastiano Cantalupo, Paul Hewett | Summary: We present optical and near-infrared imaging of the field of the z=7.0842 quasar ULAS J112001.48+064124.3 taken with the Hubble Space Telescope. We use these data to search for galaxies that may be physically associated […]

ULASJ1234+0907: The Reddest Type 1 Quasar at z=2.5 Revealed in the X-ray and Far Infra-red

Kavli Affiliate: R. G. McMahon | First 5 Authors: Manda Banerji, Andy Fabian, Richard McMahon, , | Summary: We present Herschel and XMM-Newton observations of ULASJ1234+0907 ($z=2.503$), the reddest broad-line Type 1 quasar currently known with (i-K)>7.1. Herschel observations indicate that the quasar host is a hyperluminous infrared galaxy (HyLIRG) with a total infrared luminosity […]

Classifying Supernovae Using Only Galaxy Data

Kavli Affiliate: Kaisey Mandel | First 5 Authors: Ryan J. Foley, Kaisey Mandel, , , | Summary: We present a new method for probabilistically classifying supernovae (SNe) without using SN spectral or photometric data. Unlike all previous studies to classify SNe without spectra, this technique does not use any SN photometry. Instead, the method relies […]

The Baryon Oscillation Spectroscopic Survey of SDSS-III

Kavli Affiliate: R. G. McMahon | First 5 Authors: Kyle S. Dawson, David J. Schlegel, Christopher P. Ahn, Scott F. Anderson, Éric Aubourg | Summary: The Baryon Oscillation Spectroscopic Survey (BOSS) is designed to measure the scale of baryon acoustic oscillations (BAO) in the clustering of matter over a larger volume than the combined efforts […]

4MOST – 4-metre Multi-Object Spectroscopic Telescope

Kavli Affiliate: R. G. McMahon | First 5 Authors: Roelof S. de Jong, Olga Bellido-Tirado, Cristina Chiappini, Éric Depagne, Roger Haynes | Summary: The 4MOST consortium is currently halfway through a Conceptual Design study for ESO with the aim to develop a wide-field (>3 square degree, goal >5 square degree), high-multiplex (>1500 fibres, goal 3000 […]

Sub-millimeter Detected z~2 Radio-quiet QSOs: Accurate Redshifts, Black Hole Masses, and Inflow/Outflow Velocities

Kavli Affiliate: R. G. McMahon | First 5 Authors: Gustavo Orellana, Neil M. Nagar, Kate G. Isaac, Robert Priddey, Roberto Maiolino | Summary: We present near-IR spectroscopy of a sample of luminous (Lbol >10^14 Lsun), sub-millimeter-detected, dusty (M_dust~10^9 Msun), radio-quiet QSOs at z~2. We measure the redshift, width, and luminosity of the Halpha line, and […]
