Flare-generated Shock Wave Propagation through Solar Coronal Arcade Loops and an Associated Type II Radio Burst
Innes, D. E.; Kumar, Pankaj; Cho, Kyung-Suk
This paper presents multiwavelength observations of a flare-generated type II radio burst. The kinematics of the shock derived from the type II burst closely match a fast extreme ultraviolet (EUV) wave seen propagating through coronal arcade loops. The EUV wave was closely associated with an impulsive M1.0 flare without a related coronal mass ejec…
LENSED: a code for the forward reconstruction of lenses and sources from strong lensing observations
Metcalf, R. Benton; Tessore, Nicolas; Bellagamba, Fabio
Robust modelling of strong lensing systems is fundamental to exploit the information they contain about the distribution of matter in galaxies and clusters. In this work, we present LENSED, a new code which performs forward parametric modelling of strong lenses. LENSED takes advantage of a massively parallel ray-tracing kernel to perform the neces…
A New M Dwarf Debris Disk Candidate in a Young Moving Group Discovered with Disk Detective
Kuchner, Marc J.; Gagné, Jonathan; Wisniewski, John P. +14 more
We used the Disk Detective citizen science project and the BANYAN II Bayesian analysis tool to identify a new candidate member of a nearby young association with infrared excess. WISE J080822.18-644357.3, an M5.5-type debris disk system with significant excess at both 12 and 22 µm, is a likely member (∼ 90 % BANYAN II probability) of the ∼45…
Herschel far-infrared photometry of the Swift Burst Alert Telescope active galactic nuclei sample of the local universe - II. SPIRE observations
Mushotzky, Richard F.; Cowie, Lennox L.; Barger, Amy J. +3 more
We present far-infrared (FIR) and submillimetre photometry from the Herschel Space Observatory's Spectral and Photometric Imaging Receiver (SPIRE) for 313 nearby (z < 0.05) active galactic nuclei (AGN). We selected AGN from the 58 month Swift Burst Alert Telescope (BAT) catalogue, the result of an all-sky survey in the 14-195 keV energy band, a…
Parallax Results from URAT Epoch Data
Finch, Charlie T.; Zacharias, Norbert
We present 1103 trigonometric parallaxes and proper motions from the United States Naval Observatory Robotic Astrometric Telescope (URAT) observations taken at the Naval Observatory Flagstaff Station (NOFS) over a three-year period from 2012 April to 2015 June covering the entire sky north of about -10^\circ decl. We selected two samples: previous…
Detection of Phosphorus, Sulphur, and Zinc in the Carbon-enhanced Metal-poor Star BD+44 493
Beers, Timothy C.; Placco, Vinicius M.; Roederer, Ian U.
The carbon-enhanced metal-poor star BD+44°493 ([Fe/H] = -3.9) has been proposed as a candidate second-generation star enriched by metals from a single Pop III star. We report the first detections of P and S and the second detection of Zn in any extremely metal-poor carbon-enhanced star, using new spectra of BD+44°493 collected by the Cosmic Origin…
Observations and analysis of a curved jet in the coma of comet 67P/Churyumov-Gerasimenko
Jorda, L.; Lamy, P. L.; Lara, L. M. +48 more
Aims: We analyze the physical properties and dynamical origin of a curved jet of comet 67P/Churyumov-Gerasimenko that was observed repeatedly in several nucleus rotations starting on May 30 and persisting until early August, 2015.
Methods: We simulated the motion of dust grains ejected from the nucleus surface under the influence of the …
The Million Optical - Radio/X-ray Associations (MORX) Catalogue
Flesch, Eric W.
This automated catalogue combines all the largest published optical, radio, and X-ray sky catalogues to find probable radio/X-ray associations to optical objects, plus double radio lobes, using uniform processing against all input data. The total count is 1 002 855 optical objects so presented. Each object is displayed with J2000 astrometry, optic…
Local analyses of Planck maps with Minkowski functionals
Novaes, C. P.; Bernui, A.; Ferreira, I. S. +1 more
Minkowski functionals (MF) are excellent tools to investigate the statistical properties of the cosmic background radiation (CMB) maps. Between their notorious advantages is the possibility to use them efficiently in patches of the CMB sphere, which allow studies in masked skies, inclusive analyses of small sky regions. Then, possible deviations f…
Feeding and feedback in NGC 3081
Robinson, Andrew; Schnorr-Müller, Allan; Storchi-Bergmann, Thaisa +2 more
We present two-dimensional gaseous kinematics of the inner 1.2 × 1.8 kpc2 of the Seyfert 2 galaxy NGC 3081, from optical spectra (5600-7000 Å) obtained with the Gemini Multi Object Spectrograph integral field spectrograph on the Gemini North telescope at a spatial resolution of ≈100 pc. We have identified two components in the line emit…
