Studying the YMC population of M83: how long clusters remain embedded, their interaction with the ISM and implications for GC formation theories
Bastian, N.; Ryon, J. E.; Adamo, A. +4 more
The study of young massive clusters can provide key information for the formation of globular clusters, as they are often considered analogues. A currently unanswered question in this field is how long these massive clusters remain embedded in their natal gas, with important implications for the formation of multiple populations that have been use…
The Confined X-class Flares of Solar Active Region 2192
Temmer, M.; Veronig, A. M.; Su, Y. +1 more
The unusually large active region (AR) NOAA 2192, observed in 2014 October, was outstanding in its productivity of major two-ribbon flares without coronal mass ejections. On a large scale, a predominantly north-south oriented magnetic system of arcade fields served as a strong top and lateral confinement for a series of large two-ribbon flares ori…
The exceptionally powerful TeV γ-ray emitters in the Large Magellanic Cloud
Klochkov, D.; Santangelo, A.; Quirrenbach, A. +226 more
The Large Magellanic Cloud, a satellite galaxy of the Milky Way, has been observed with the High Energy Stereoscopic System (H.E.S.S.) above an energy of 100 billion electron volts for a deep exposure of 210 hours. Three sources of different types were detected: the pulsar wind nebula of the most energetic pulsar known, N 157B; the radio-loud supe…
The MOSDEF Survey: Dissecting the Star Formation Rate versus Stellar Mass Relation Using Hα and Hβ Emission Lines at z ∼ 2
Siana, Brian; Shapley, Alice E.; Reddy, Naveen A. +9 more
We present results on the star formation rate (SFR) versus stellar mass (M*) relation (i.e., the “main sequence”) among star-forming galaxies at 1.37 ≤ z ≤ 2.61 using the MOSFIRE Deep Evolution Field (MOSDEF) survey. Based on a sample of 261 galaxies with Hα and Hβ spectroscopy, we have estimated robust dust-corrected instantaneous SFRs…
High-mass Star Formation Triggered by Collision between CO Filaments in N159 West in the Large Magellanic Cloud
Lebouteiller, Vianney; Inoue, Tsuyoshi; Tokuda, Kazuki +20 more
We have carried out 13CO(J = 2-1) observations of the active star-forming region N159 west in the Large Magellanic Cloud with ALMA. We have found that the CO distribution at a sub-parsec scale is highly elongated with a small width. These elongated clouds called “filaments” show straight or curved distributions with a typical width of 0…
The JCMT Gould Belt Survey: first results from the SCUBA-2 observations of the Ophiuchus molecular cloud and a virial analysis of its prestellar core population
White, G. J.; André, Ph.; Könyves, V. +59 more
In this paper, we present the first observations of the Ophiuchus molecular cloud performed as part of the James Clerk Maxwell Telescope (JCMT) Gould Belt Survey (GBS) with the SCUBA-2 instrument. We demonstrate methods for combining these data with previous HARP CO, Herschel, and IRAM N2H+ observations in order to accurately…
A Critical Assessment of Stellar Mass Measurement Methods
Finkelstein, Steven L.; Barro, Guillermo; Santini, Paola +34 more
This is the second paper in a series aimed at investigating the main sources of uncertainty in measuring the observable parameters in galaxies from their spectral energy distributions (SEDs). In the first paper we presented a detailed account of the photometric redshift measurements and an error analysis of this process. In this paper we perform a…
A Measurement of the Cosmic Microwave Background Gravitational Lensing Potential from 100 Square Degrees of SPTpol Data
Ade, P. A. R.; Chiang, H. C.; Hanson, D. +63 more
We present a measurement of the cosmic microwave background (CMB) gravitational lensing potential using data from the first two seasons of observations with SPTpol, the polarization-sensitive receiver currently installed on the South Pole Telescope. The observations used in this work cover 100 deg2 of sky with arcminute resolution at 15…
Properties of the 67P/Churyumov-Gerasimenko interior revealed by CONSERT radar
Elachi, Charles; Sierks, Holger; Nielsen, Erling +23 more
The Philae lander provides a unique opportunity to investigate the internal structure of a comet nucleus, providing information about its formation and evolution in the early solar system. We present Comet Nucleus Sounding Experiment by Radiowave Transmission (CONSERT) measurements of the interior of Comet 67P/Churyumov-Gerasimenko. From the propa…
Flare-CME Models: An Observational Perspective (Invited Review)
Aulanier, G.; Vršnak, B.; Schmieder, B.
Eruptions, flares, and coronal mass ejection (CMEs) are due to physical phenomena mainly driven by an initially force-free current-carrying magnetic field. We review some key observations relevant to the current theoretical trigger mechanisms of the eruption and to the energy release via reconnection. Sigmoids observed in X-rays and UV, as well as…
