Rapid radio flaring during an anomalous outburst of SS Cyg
Miller-Jones, J. C. A.; Fender, R. P.; Mooley, K. P. +12 more
The connection between accretion and jet production in accreting white dwarf binary systems, especially dwarf novae, is not well understood. Radio wavelengths provide key insights into the mechanisms responsible for accelerating electrons, including jets and outflows. Here, we present densely sampled radio coverage, obtained with the Arcminute Mic…
De-blending deep Herschel surveys: A multi-wavelength approach
Burgarella, D.; Wang, L.; Oliver, S. J. +3 more
Aims: Cosmological surveys in the far-infrared are known to suffer from confusion. The Bayesian de-blending tool, XID+, currently provides one of the best ways to de-confuse deep Herschel SPIRE images, using a flat flux density prior. This work is to demonstrate that existing multi-wavelength data sets can be exploited to improve XID+ by prov…
Catalog of equatorial coordinates and B-magnitudes of stars of the Kitab part of the FON project
Ehgamberdiev, Sh. A.; Andruk, V. M.; Muminov, M. M. +3 more
The processing of the plates of the Kitab part of the FON project has been completed. In total, 1963 plates were processed. The catalog of equatorial coordinates α, δ, and B-magnitudes for 13 413268 stars and galaxies up to B ≤ 17.5m for the epoch 1984.97 is compiled. The Epson Expression 10000XL scanner with a 1200 dpi scanning mode an…
K2-60b and K2-107b. A Sub-Jovian and a Jovian Planet from the K2 Mission
Cochran, William D.; Endl, Michael; Gandolfi, Davide +20 more
We report the characterization and independent detection of K2-60b, as well as the detection and characterization of K2-107b, two transiting hot gaseous planets from the K2 space mission. We confirm the planetary nature of the two systems and determine their fundamental parameters combining the K2 time-series data with FIES@NOT and HARPS-N@TNG spe…
Far-infrared Properties of Infrared-bright Dust-obscured Galaxies Selected with IRAS and AKARI Far-infrared All-sky Survey
Goto, Tomotsugu; Yamamura, Issei; Koyama, Yusei +6 more
We investigate the star-forming activity of a sample of infrared (IR)-bright dust-obscured galaxies (DOGs) that show an extreme red color in the optical and IR regime, {(I-[22])}{AB}> 7.0. Combining an IR-bright DOG sample with the flux at 22 µm > 3.8 mJy discovered by Toba & Nagao with the IRAS faint source catalog vers…
Hot Gas in the Wolf-Rayet Nebula NGC 3199
Gruendl, R. A.; Marston, A. P.; Chu, Y. -H. +2 more
The Wolf-Rayet (WR) nebula NGC 3199 has been suggested to be a bow shock around its central star, WR 18, which is presumably a runaway star, because optical images of the nebula show a dominating arc of emission southwest of the star. We present the XMM-Newton detection of extended X-ray emission from NGC 3199, unveiling the powerful effect of the…
Planck's dusty GEMS. III. A massive lensing galaxy with a bottom-heavy stellar initial mass function at z = 1.5
Kneissl, R.; Le Floc'h, E.; Dole, H. +8 more
We study the properties of the foreground galaxy of the Ruby, the brightest gravitationally lensed high-redshift galaxy on the sub-millimeter sky as probed by the Planck satellite, and part of our sample of Planck's dusty GEMS. The Ruby consists of an Einstein ring of 1.4'' diameter at z = 3.005 observed with ALMA at 0.1'' resolution, centered on …
Modeling Type II-P/II-L Supernovae Interacting with Recent Episodic Mass Ejections from Their Presupernova Stars with MESA and SNEC
Das, Sanskriti; Ray, Alak
We show how dense, compact, discrete shells of circumstellar gas immediately outside of red supergiants affect the optical light curves of Type II-P/II-L supernovae (SNe), using the example of SN 2013ej. Earlier efforts in the literature had used an artificial circumstellar medium (CSM) stitched to the surface of an evolved star that had not gone …

Detection of faint broad emission lines in type 2 AGN - I. Near-infrared observations and spectral fitting
Maiolino, R.; Fiore, F.; Bianchi, S. +8 more
We present medium resolution near-infrared spectroscopic observations of 41 obscured and intermediate class active galactic nuclei (AGN; type 2, 1.9 and 1.8; AGN2) with redshift z ≲ 0.1, selected from the Swift/Burst Alert Telescope 70-month catalogue. The observations have been carried out in the framework of a systematic study of the AGN2 near-i…
