The Luminous Blue Variable RMC 127 as Seen with ALMA and ATCA
Paladini, R.; Umana, G.; Bauer, F. E. +12 more
We present ALMA and ATCA observations of the luminous blue variable RMC 127. The radio maps show for the first time the core of the nebula and evidence that the nebula is strongly asymmetric with a Z-pattern shape. Hints of this morphology are also visible in the archival Hubble Space Telescope {{H}}α image, which overall resembles the radio emiss…
3XMM J181923.7-170616: An X-Ray Binary with a 408 s Pulsar
Qiu, Hao; Zhou, Ping; Xu, Xiaojie +2 more
We carry out a dedicated study of 3XMM J181923.7-170616 with an approximate pulsation period of 400 s using the XMM-Newton and Swift observations spanning across nine years. We have refined the period of the source to 407.904(7) s (at epoch MJD 57142) and constrained the 1σ upper limit on the period derivative \dot{P}≤slant 1.1× {10}-8 …
A Molecular-line Study of the Interstellar Bullet Engine IRAS05506+2414
Morris, Mark R.; Lee, Chin-Fei; Patel, Nimesh +3 more
We present interferometric and single-dish molecular line observations of the interstellar bullet-outflow source IRAS 05506+2414, whose wide-angle bullet spray is similar to the Orion BN/KL explosive outflow and likely arises from an entirely different mechanism than the classical accretion-disk-driven bipolar flows in young stellar objects. The b…
Spectral Energy Distribution Mapping of Two Elliptical Galaxies on Sub-kpc Scales
Gaspari, M.; Amblard, A.; Temi, P. +1 more
We use high-resolution Herschel-PACS data of two nearby elliptical galaxies, IC 1459 and NGC 2768, to characterize their dust and stellar content. IC 1459 and NGC 2768 have an unusually large amount of dust for elliptical galaxies ((1-3) × 105 {M}⊙ ); this dust is also not distributed along the stellar content. Using data fro…
Dependence of the Peak Fluxes of Solar Energetic Particles on CME 3D Parameters from STEREO and SOHO
Moon, Y. -J.; Lee, Harim; Park, Jinhye
We investigate the relationships between the peak fluxes of 18 solar energetic particle (SEP) events and associated coronal mass ejection (CME) 3D parameters (speed, angular width, and separation angle) obtained from SOHO, and STEREO-A/B for the period from 2010 August to 2013 June. We apply the STEREO CME Analysis Tool (StereoCAT) to the SEP-asso…

Resolving the Discrepancy of Distance to M60, a Giant Elliptical Galaxy in Virgo
Lee, Myung Gyoon; Jang, In Sung
There is a well-known discrepancy in the distance estimation of M60, a giant elliptical galaxy in Virgo; the planetary nebula luminosity function (PNLF) distance moduli for this galaxy are, on average, 0.4 mag smaller than the values based on the surface brightness fluctuation (SBF) in the literature. We present photometry of the resolved stars in…
Spitzer’s View of the Candidate Cluster and Protocluster Catalog (CCPC)
Franck, J. R.; McGaugh, S. S.
The Candidate Cluster and Protocluster Catalog contains 218 galaxy overdensities composed of more than 2000 galaxies with spectroscopic redshifts spanning the first few Gyr after the Big Bang (2.0 ≤ z < 6.6). We use Spitzer archival data to track the underlying stellar mass of these overdense regions in various temporal cross sections by buildi…
The Hawaii SCUBA-2 Lensing Cluster Survey: Are Low-luminosity Submillimeter Galaxies Detected in the Rest-frame UV?
Wang, Wei-Hao; Cowie, Lennox L.; Barger, Amy J. +1 more
In this third paper of the Hawaii SCUBA-2 Lensing Cluster Survey series, we present Submillimeter Array (SMA) detections of six intrinsically faint 850 µm sources detected in SCUBA-2 images of the lensing cluster fields, A1689, A2390, A370, MACS J0717.5+3745, and MACS J1423.8+2404. Two of the SCUBA-2 sources split into doublets, yielding a t…
The BRAVE Program. I. Improved Bulge Stellar Velocity Dispersion Estimates for a Sample of Active Galaxies
Bershady, Matthew A.; Onken, Christopher A.; Bentz, Misty C. +2 more
We present new bulge stellar velocity dispersion measurements for 10 active galaxies with secure MBH determinations from reverberation mapping. These new velocity dispersion measurements are based on spatially resolved kinematics from integral-field (IFU) spectroscopy. In all but one case, the field of view of the IFU extends beyond the…
