Fine and Superfine Structure of the Decameter-Hectometer Type II Burst on 7 June 2011
Panchenko, M.; Poedts, S.; Konovalenko, A. A. +4 more
The characteristics of a type II burst with a herringbone structure observed both with ground-based radio telescopes (UTR-2 and URAN-2) and space-borne spectrometers (STEREO-A and B) are discussed. The burst was recorded on 7 June 2011 in the frequency band 3 - 33 MHz. It was characterized by extremely rich fine structure. Statistical analysis of …
Differentiation signatures in the Flora region
Oszkiewicz, Dagmara; Włodarczyk, Ireneusz; Kankiewicz, Paweł +1 more
Context. Most asteroid families are very homogeneous in physical properties. Some show greater diversity, however. The Flora family is the most intriguing of them. The Flora family is spread widely in the inner main belt, has a rich collisional history, and is one of the most taxonomically diverse regions in the main belt. As a result of its proxi…
A Low-mass Main-sequence Star and Accretion Disk in the Very Faint X-Ray Transient M15 X-3
Heinke, C. O.; Cohn, H. N.; Lugger, P. M. +2 more
We present near-simultaneous {\text{}}{Chandra}/Hubble Space Telescope ({\text{}}{HST}) observations of the very faint (Lx < 1036 erg s-1) X-ray transient source M15 X-3, as well as unpublished archival {\text{}}{Chandra} observations of M15 X-3. The {\text{}}{Chandra} observations constrain the luminosity of M1…
The Swift X-Ray Telescope Cluster Survey. III. Cluster Catalog from 2005-2012 Archival Data
Giavalisco, Mauro; Rosati, Piero; Tozzi, Paolo +6 more
We present the Swift X-ray Cluster Survey (SWXCS) catalog obtained using archival data from the X-ray telescope (XRT) on board the Swift satellite acquired from 2005 February to 2012 November, extending the first release of the SWXCS. The catalog provides positions, soft fluxes, and, when possible, optical counterparts for a flux-limited sample of…
The effect of diamagnetic drift on motion of the dayside magnetopause reconnection line
Fear, R. C.; Marcucci, M. F.; Trenchi, L.
Magnetic reconnection at the magnetopause occurs with a large density asymmetry and for a large range of magnetic shears. In these conditions, a motion of the X line has been predicted in the direction of the electron diamagnetic drift. When this motion is super Alfvenic, reconnection should be suppressed. We analysed a large data set of Double St…
Surface thermophysical properties determination of OSIRIS-REx target asteroid (101955) Bennu
Yu, LiangLiang; Ji, Jianghui
In this work, we investigate the thermophysical properties of OSIRIS-REx target asteroid (101955) Bennu (hereafter Bennu), where thermal inertia plays an important role in understanding the nature of the asteroid's surface, and will definitely provide substantial information for the sampling return mission. Using a thermophysical model incorporati…
Possible evidence for Planck-scale resonant particle production during inflation from the CMB power spectrum
Mathews, G. J.; Gangopadhyay, M. R.; Ichiki, K. +1 more
The power spectrum of the cosmic microwave background from both the Planck and WMAP data exhibits a slight dip for multipoles in the range of l =10 - 30 . We show that such a dip could be the result of the resonant creation of massive particles that couple to the inflaton field. For our best-fit models, the epoch of resonant particle creation reen…
HST Astrometry in the 30 Doradus Region: Measuring Proper Motions of Individual Stars in the Large Magellanic Cloud
Anderson, Jay; van der Marel, Roeland P.; Sana, Hugues +5 more
We present measurements of positions and relative proper motions in the 30 Doradus region of the LMC. We detail the construction of a single-epoch astrometric reference frame, based on specially designed observations obtained with the two main imaging instruments Advanced Camera for Surveys/Wide Field Channel and Wide Field Camera 3/UVIS on board …
Discovery of Massive, Mostly Star Formation Quenched Galaxies with Extremely Large Lyα Equivalent Widths at z ∼ 3
Koekemoer, Anton M.; Tresse, Laurence; Schinnerer, Eva +21 more
We report a discovery of six massive galaxies with both extremely large Lyα equivalent widths (EWs) and evolved stellar populations at z ∼ 3. These MAssive Extremely STrong Lyα emitting Objects (MAESTLOs) have been discovered in our large-volume systematic survey for strong Lyα emitters (LAEs) with 12 optical intermediate-band data taken with Suba…
Measurements of the Sunyaev-Zel'dovich Effect in MACS J0647.7+7015 and MACS J1206.2-0847 at High Angular Resolution with MUSTANG
Mroczkowski, Tony; Umetsu, Keiichi; Nonino, Mario +18 more
We present high resolution (9″) imaging of the Sunyaev-Zel’dovich Effect (SZE) toward two massive galaxy clusters, MACS J0647.7+7015 (z = 0.591) and MACS J1206.2-0847 (z = 0.439). We compare these 90 GHz measurements, taken with the Multiplexed Squid/TES Array at Ninety Gigahertz (MUSTANG ) receiver on the Green Bank Telescope, with generalized Na…
