Hubble Space Telescope Imaging of the Active Dwarf Galaxy RGG 118

DOI: 10.3847/1538-4357/aa9067 Bibcode: 2017ApJ...850..196B

Greene, Jenny E.; Baldassare, Vivienne F.; Reines, Amy E. +1 more

RGG 118 (SDSS 1523+1145) is a nearby (z = 0.0243), dwarf disk galaxy ({M}_*≈ 2× {10}⁹ {M}_⊙) that is found to host an active ∼50,000 solar mass black hole at its core. RGG 118 is one of a growing collective sample of dwarf galaxies known to contain active galactic nuclei (AGNs)—a group that, until recently, contain…

Expelled grains from an unseen parent body around AU Microscopii

DOI: 10.1051/0004-6361/201731061 Bibcode: 2017A&A...607A..65S

Augereau, J. -C.; Boccaletti, A.; Sezestre, É. +1 more

Context. Recent observations of the edge-on debris disk of AU Mic have revealed asymmetric, fast outward-moving arch-like structures above the disk midplane. Although asymmetries are frequent in debris disks, no model can readily explain the characteristics of these features.
Aims: We present a model aiming to reproduce the…

Quasar lenses and galactic streams: outlier selection and Gaia multiplet detection

DOI: 10.1093/mnras/stx1650 Bibcode: 2017MNRAS.471.2013A

Agnello, Adriano

I describe two novel techniques originally devised to select strongly lensed quasar candidates in wide-field surveys. The first relies on outlier selection in optical and mid-infrared magnitude space; the second combines mid-infrared colour selection with Gaia spatial resolution, to identify multiplets of objects with quasar-like colours. Both met…

Sheath-accumulating Propagation of Interplanetary Coronal Mass Ejection

DOI: 10.3847/2041-8213/aa624c Bibcode: 2017ApJ...837L..17T

Shibata, Kazunari; Takahashi, Takuya

Fast interplanetary coronal mass ejections (ICMEs) are the drivers of strong space weather storms such as solar energetic particle events and geomagnetic storms. The connection between the space-weather-impacting solar wind disturbances associated with fast ICMEs at Earth and the characteristics of causative energetic CMEs observed near the Sun is…

Statistics of the fractional polarization of compact radio sources in Planck maps

DOI: 10.1093/mnras/stx1020 Bibcode: 2017MNRAS.469.2401B

Toffolatti, Luigi; Bonavera, Laura; González-Nuevo, Joaquin +1 more

In this work, we apply the stacking technique to estimate the average fractional polarization from 30 to 353 GHz of a primary sample of 1560 compact sources - essentially all radio sources - detected in the 30 GHz Planck all-sky map and listed in the second version of the Planck Catalogue of Compact Sources (PCCS2). We divide our primary sample in…

Multiband study of RX J0838-2827 and XMM J083850.4-282759: a new asynchronous magnetic cataclysmic variable and a candidate transitional millisecond pulsar

DOI: 10.1093/mnras/stx1560 Bibcode: 2017MNRAS.471.2902R

D'Avanzo, P.; Campana, S.; Ribas, I. +23 more

In a search for the counterpart to the Fermi-LAT source 3FGL J0838.8-2829, we performed a multiwavelength campaign: in the X-ray band with Swift and XMM-Newton; in the infrared and optical with OAGH, ESO-NTT and IAC80; and in the radio with ATCA observations. We also used archival hard X-ray data obtained by INTEGRAL. We report on three X-ray sour…

An extension of the Planck galaxy cluster catalogue

DOI: 10.1134/S1063773717080035 Bibcode: 2017AstL...43..507B

Burenin, R. A.

We present a catalogue of galaxy clusters detected in the Planck all-sky Compton parameter maps and identified using data from the WISE and SDSS surveys. The catalogue comprises about 3000 clusters in the SDSS fields. We expect the completeness of this catalogue to be high for clusters with masses larger than M ₅₀₀ ≈ 3 × 10¹⁴…

Triggering Process of the X1.0 Three-ribbon Flare in the Great Active Region NOAA 12192

DOI: 10.3847/1538-4357/aa6682 Bibcode: 2017ApJ...838..134B

Kusano, Kanya; Shiota, Daikou; Inoue, Satoshi +1 more

The solar magnetic field in a flare-producing active region (AR) is much more complicated than theoretical models, which assume a very simple magnetic field structure. The X1.0 flare, which occurred in AR 12192 on 2014 October 25, showed a complicated three-ribbon structure. To clarify the trigger process of the flare and to evaluate the applicabi…

How pristine is the interior of the comet 67P/Churyumov-Gerasimenko?

DOI: 10.1093/mnras/stx2627 Bibcode: 2017MNRAS.469S.685C

Longobardo, Andrea; Palomba, Ernesto; Zinzi, Angelo +14 more

Comets are usually considered to be the most primitive bodies in the Solar System. The level of truth of this paradigm, however, is a matter of debate, especially if by primitive we mean that they represent a sample of intact, unprocessed material. We now have the possibility of analysing the comet 67P/Churyumov-Gerasimenko with an unprecedented l…
