The Interstellar Medium in High-redshift Submillimeter Galaxies as Probed by Infrared Spectroscopy*

DOI: 10.3847/1538-4357/837/1/12 Bibcode: 2017ApJ...837...12W

Smith, Matthew W. L.; van der Werf, Paul; Valtchanov, Ivan +21 more

Submillimeter galaxies (SMGs) at z≳ 1 are luminous in the far-infrared, and have star formation rates, SFR, of hundreds to thousands of solar masses per year. However, it is unclear whether they are true analogs of local ULIRGs or whether the mode of their star formation is more similar to that in local disk galaxies. We target these questions by …

Exposure age of Saturn's A and B rings, and the Cassini Division as suggested by their non-icy material content

DOI: 10.1016/j.icarus.2017.04.008 Bibcode: 2017Icar..294...14Z

Nicholson, P. D.; Janssen, M. A.; Hayes, A. G. +4 more

Saturn's rings are composed primarily of water ice with a small fraction of non-icy constituents that are likely both intrinsic and extrinsic in origin. The intrinsic material is thought to be characteristic of the ring progenitor, while the extrinsic material is derived from the continual stream of hypervelocity impacting micrometeoroids that pol…

First Detection of Prominence Material Embedded within a 2 × 10⁶ K CME Front Streaming away at 100-1500 km s^-1 in the Solar Corona

DOI: 10.3847/2041-8213/aa7460 Bibcode: 2017ApJ...842L...7D

Habbal, Shadia Rifai; Ding, Adalbert

Coronal mass ejections (CMEs) are the largest and most dynamic explosions detected in the million degree solar corona, with speeds reaching up to 3000 km s^-1 at Earth’s orbit. Triggered by the eruption of prominences, in most cases, one of the outstanding questions pertaining to the dynamic CME-prominence system is the fate of the cool …

Computational helioseismology in the frequency domain: acoustic waves in axisymmetric solar models with flows

DOI: 10.1051/0004-6361/201629470 Bibcode: 2017A&A...600A..35G

Gizon, Laurent; Birch, Aaron C.; Fournier, Damien +7 more

Context. Local helioseismology has so far relied on semi-analytical methods to compute the spatial sensitivity of wave travel times to perturbations in the solar interior. These methods are cumbersome and lack flexibility.
Aims: Here we propose a convenient framework for numerically solving the forward problem of time-distance helioseismology…

DHIGLS: DRAO H I Intermediate Galactic Latitude Survey

DOI: 10.3847/1538-4357/834/2/126 Bibcode: 2017ApJ...834..126B

Martin, P. G.; Kothes, R.; Lockman, Felix J. +5 more

Observations of Galactic H I gas for seven targeted regions at intermediate Galactic latitude are presented at 1^\prime angular resolution using data from the DRAO Synthesis Telescope (ST) and the Green Bank Telescope (GBT). The DHIGLS data are the most extensive arcminute-resolution measurements of the diffuse atomic interstellar medium…

Optical spectroscopic observations of gamma-ray blazar candidates. VII. Follow-up campaign in the southern hemisphere

DOI: 10.1007/s10509-017-3208-7 Bibcode: 2017Ap&SS.362..228P

Masetti, N.; Jiménez-Bailón, E.; Cheung, C. C. +15 more

Searching for low energy counterparts of γ-rays sources is one of the major challenges in modern γ-ray astronomy. In the third Fermi source catalog about 30% of detected sources are unide…

Non-Maxwellian Analysis of the Transition-region Line Profiles Observed by the Interface Region Imaging Spectrograph

DOI: 10.3847/1538-4357/aa71a8 Bibcode: 2017ApJ...842...19D

Polito, Vanessa; Del Zanna, Giulio; Testa, Paola +2 more

We investigate the nature of the spectral line profiles for transition-region (TR) ions observed with the Interface Region Imaging Spectrograph (IRIS). In this context, we analyzed an active-region observation performed by IRIS in its 1400 Å spectral window. The TR lines are found to exhibit significant wings in their spectral profiles, which can …

Solar Magnetoconvection and Small-Scale Dynamo. Recent Developments in Observation and Simulation

DOI: 10.1007/s11214-015-0204-5 Bibcode: 2017SSRv..210..275B

Solanki, S. K.; Borrero, J. M.; Schüssler, M. +1 more

A number of observational and theoretical aspects of solar magnetoconvection are considered in this review. We discuss recent developments in our understanding of the small-scale structure of the magnetic field on the solar surface and its interaction with convective flows, which is at the centre of current research. Topics range from plage areas …

Cloud Structure of Three Galactic Infrared Dark Star-forming Regions from Combining Ground- and Space-based Bolometric Observations

DOI: 10.3847/1538-4357/aa6c67 Bibcode: 2017ApJ...840...22L

Li, Di; Qian, Lei; Ginsburg, Adam +12 more

We have modified the iterative procedure introduced by Lin et al., to systematically combine the submillimeter images taken from ground-based (e.g., CSO, JCMT, APEX) and space (e.g., Herschel, Planck) telescopes. We applied the updated procedure to observations of three well-studied Infrared Dark Clouds (IRDCs): G11.11-0.12, G14.225-0.506, and G28…
