The Runaways and Isolated O-Type Star Spectroscopic Survey of the SMC (RIOTS4)
Oey, M. S.; Parker, J. Wm.; Kiminki, D. C. +4 more
We present the Runaways and Isolated O-Type Star Spectroscopic Survey of the SMC (RIOTS4), a spatially complete survey of uniformly selected field OB stars that covers the entire star-forming body of the Small Magellanic Cloud (SMC). Using the IMACS (Inamori-Magellan Areal Camera and Spectrograph) multislit spectrograph and MIKE (Magellan Inamori …
Relationship of EUV Irradiance Coronal Dimming Slope and Depth to Coronal Mass Ejection Speed and Mass
Vourlidas, Angelos; Colaninno, Robin C.; Woods, Thomas N. +3 more
Extreme ultraviolet (EUV) coronal dimmings are often observed in response to solar eruptive events. These phenomena can be generated via several different physical processes. For space weather, the most important of these is the temporary void left behind by a coronal mass ejection (CME). Massive, fast CMEs tend to leave behind a darker void that …
The SCUBA-2 Cosmology Legacy Survey: Multiwavelength Counterparts to 103 Submillimeter Galaxies in the UKIDSS-UDS Field
Zavala, Jorge A.; Smail, Ian; Conselice, Christopher J. +20 more
We present multiwavelength identifications for the counterparts of 1088 submillimeter sources detected at 850 µm in the SCUBA-2 Cosmology Legacy Survey study of the UKIRT Infrared Deep Sky Survey-Ultra-Deep Survey (UDS) field. By utilizing an Atacama Large Millimeter Array (ALMA) pilot study on a subset of our bright SCUBA-2 sample as a trai…
Detection of a Possible X-Ray Quasi-periodic Oscillation in the Active Galactic Nucleus 1H 0707-495
Yuan, Weimin; Zhang, Shuang-Nan; Pan, Hai-Wu +4 more
The quasi-periodic oscillation (QPO) detected in the X-ray radiation of black hole X-ray binaries (BHXBs) is thought to originate from dynamical processes in close vicinity of black holes (BHs), and thus carries important physical information therein. Such a feature is extremely rare in active galactic nuclei (AGNs) with supermassive BHs. Here we …
The Panchromatic Hubble Andromeda Treasury. XV. The BEAST: Bayesian Extinction and Stellar Tool
Bell, Eric F.; Skillman, Evan D.; Williams, Benjamin F. +17 more
We present the Bayesian Extinction And Stellar Tool (BEAST), a probabilistic approach to modeling the dust extinguished photometric spectral energy distribution of an individual star while accounting for observational uncertainties common to large resolved star surveys. Given a set of photometric measurements and an observational uncertainty model…
Satellite Quenching and Galactic Conformity at 0.3 < z < 2.5
Papovich, Casey; Kelson, Daniel D.; Kacprzak, Glenn G. +21 more
We measure the evolution of the quiescent fraction and quenching efficiency of satellites around star-forming and quiescent central galaxies with stellar mass {log}({M}{cen}/{M}⊙ )\gt 10.5 at 0.3\lt z\lt 2.5. We combine imaging from three deep near-infrared-selected surveys (ZFOURGE/CANDELS, Ultra Deep Survey, and UltraVISTA)…
A Mature Galaxy Cluster at z=1.58 around the Radio Galaxy 7C1753+6311
Stern, D.; Conselice, C. J.; Brodwin, M. +9 more
We report on the discovery of a z = 1.58 mature cluster around the high-redshift radio galaxy 7C 1753+6311, first identified in the Clusters Around Radio-loud active galactic nuclei survey. Two-thirds of the excess galaxies within the central 1 Mpc lie on a red sequence with a color that is consistent with an average formation redshift of zf<…
The 2012 July 23 Backside Eruption: An Extreme Energetic Particle Event?
Gopalswamy, N.; Yashiro, S.; Mäkelä, P. +3 more
The backside coronal mass ejection (CME) of 2012 July 23 had a short Sun-to-Earth shock transit time (18.5 hr). The associated solar energetic particle (SEP) event had a >10 MeV proton flux peaking at ∼5000 pfu, and the energetic storm particle event was an order of magnitude larger, making it the most intense event in the space era at these en…
Young Galaxy Candidates in the Hubble Frontier Fields. III. MACS J0717.5+3745
Pérez-Fournon, I.; Marques-Chaves, R.; Shu, X. +16 more
In this paper we present the results of our search for and study of z≳ 6 galaxy candidates behind the third Frontier Fields (FFs) cluster, MACS J0717.5+3745, and its parallel field, combining data from Hubble and Spitzer. We select 39 candidates using the Lyman break technique, for which the clear non-detection in optical make the extreme mid-z in…
The First Low-mass Black Hole X-Ray Binary Identified in Quiescence Outside of a Globular Cluster
Maccarone, T. J.; Heinke, C. O.; Miller-Jones, J. C. A. +9 more
The observed relation between the X-ray and radio properties of low-luminosity accreting black holes (BHs) has enabled the identification of multiple candidate black hole X-ray binaries (BHXBs) in globular clusters (GCs). Here, we report an identification of the radio source VLA J213002.08+120904 (aka M15 S2), recently reported in Kirsten et al., …
