AMiBA: Cluster Sunyaev-Zel’dovich Effect Observations with the Expanded 13-element Array

DOI: 10.3847/0004-637X/830/2/91 Bibcode: 2016ApJ...830...91L

Koch, Patrick M.; Umetsu, Keiichi; Ho, Paul T. P. +35 more

The Yuan-Tseh Lee Array for Microwave Background Anisotropy (AMiBA) is a co-planar interferometer array operating at a wavelength of 3 mm to measure the Sunyaev-Zel’dovich effect (SZE) of galaxy clusters at arcminute scales. The first phase of operation—with a compact 7-element array with 0.6 m antennas (AMiBA-7)—observed six clusters at angular s…

The Swift AGN and Cluster Survey. II. Cluster Confirmation with SDSS Data

DOI: 10.3847/0067-0049/222/1/13 Bibcode: 2016ApJS..222...13G

Bregman, Joel N.; Kochanek, Christopher S.; Dai, Xinyu +1 more

We study 203 (of 442) Swift AGN and Cluster Survey extended X-ray sources located in the SDSS DR8 footprint to search for galaxy over-densities in three-dimensional space using SDSS galaxy photometric redshifts and positions near the Swift cluster candidates. We find 104 Swift clusters with a >3σ galaxy over-density. The remaining targets are p…

Fast inversion of Zeeman line profiles using central moments. II. Stokes V moments and determination of vector magnetic fields

DOI: 10.1051/0004-6361/201525769 Bibcode: 2016A&A...591A..64M

Bommier, V.; Mein, P.; Mein, N. +2 more

Context. In the case of unresolved solar structures or stray light contamination, inversion techniques using four Stokes parameters of Zeeman profiles cannot disentangle the combined contributions of magnetic and nonmagnetic areas to the observed Stokes I.
Aims: In the framework of a two-component model atmosphere with filling factor f, we pr…

A new investigation of the possible X-ray counterparts of the magnetar candidate AX J1845-0258

DOI: 10.1093/mnras/stw1036 Bibcode: 2016MNRAS.460.1033P

Pintore, Fabio; Mereghetti, Sandro

AX J1845-0258 is a transient X-ray pulsar, with spin period of 6.97 s, discovered with the ASCA satellite in 1993. Its soft spectrum and the possible association with a supernova remnant suggest that AX J1845-0258 might be a magnetar, but this has not been confirmed yet. A possible counterpart one order of magnitude fainter, AX J184453-025640, has…

KOSMA ¹²CO(2–1) and (3–2) observations toward Infrared Dark Clouds

DOI: 10.1007/s10509-016-2807-z Bibcode: 2016Ap&SS.361..220L

Li, Dalei; Tang, Xindi; Zhou, Jianjun +7 more

Infrared Dark Clouds (IRDCs) are a valuable sample to study the initial conditions and the very early stages of the evolution of massive stars. Using the KOSMA telescope, we performed simultaneous single point ¹²CO(2–1) and (3–2) observations toward 117 IRDCs with a detection rate of 74 % for ¹²CO(2–1) and 58 % for ¹²

Statistically Determined Dispersion Relations of Magnetic Field Fluctuations in the Terrestrial Foreshock

DOI: 10.3847/0004-637X/827/2/91 Bibcode: 2016ApJ...827...91H

Nakariakov, V. M.; Hnat, B.; O'Connell, D. +1 more

We obtain dispersion relations of magnetic field fluctuations for two crossings of the terrestrial foreshock by Cluster spacecraft. These crossings cover plasma conditions that differ significantly in their plasma β and in the density of the reflected ion beam, but not in the properties of the encountered ion population, both showing shell-like di…

UV and X-ray variability of the narrow-line Seyfert 1 galaxy Ark 564

DOI: 10.1088/1674-4527/16/7/108 Bibcode: 2016RAA....16..108E

Dewangan, Gulab C.; Kembhavi, Ajit K.; Misra, Ranjeev +3 more

We analyze eight XMM-Newton observations of the bright Narrow Line Seyfert 1 galaxy Arakelian 564 (Ark 564). These observations, separated by ∼ 6 days, allow us to look for correlations between the simultaneous ultraviolet (UV) emission (from the Optical Monitor) with not only the X-ray flux but also with different X-ray spectral parameters. The X…

"Hello, World!" Harnessing Social Media for the Rosetta Mission

Bibcode: 2016CAPJ...19...30B

Bauer, M.; McCaughrean, M.; O'Flaherty, K. S. +8 more

The European Space Agency's comet-chasing Rosetta mission was launched in 2004, before social media became a popular tool for mainstream communication. As it reached its destination ten years later, new audiences were reached and inspired by this once-in-a-lifetime event by harnessing a range of outlets for communicating the key messages. These in…

A likely inverse-Compton emission from the Type IIb SN 2013df

DOI: 10.1038/srep30638 Bibcode: 2016NatSR...630638L

Kong, A. K. H.; Li, K. L.

The inverse-Compton X-ray emission model for supernovae has been well established to explain the X-ray properties of many supernovae for over 30 years. However, no observational case has yet been found to connect the X-rays with the optical lights as they should be. Here, we report the discovery of a hard X-ray source that is associated with a Typ…
