First hard X-ray detection of the non-thermal emission around the Arches cluster: morphology and spectral studies with NuSTAR

Roman A. Krivonos, John A. Tomsick, Franz E. Bauer +15

The Arches cluster is a young, densely packed massive star cluster in our Galaxy that shows a high level of star formation activity. The nature of the extended non-thermal X-ray em…

The curious morphology and orientation of Orion proplyd HST-10

Ralph Y. Shuping, Marc Kassis, John Bally +1

HST-10 is one of the largest proplyds in the Orion Nebula and is located approximately 1' SE of the Trapezium. Unlike other proplyds in Orion, however, the long-axis of HST-10 does…

Investigating Active Galactic Nuclei Variability Using Combined Multi-Quarter Kepler Data

Mitchell Revalski, Dawid Nowak, Paul J. Wiita +2

We have used photometry from the Kepler satellite to characterize the variability of four radio-loud active galactic nuclei (AGN) on timescales from years to minutes. The Kepler sa…

Aligned grains and inferred toroidal magnetic fields in the envelopes of massive young stellar objects

Janet P. Simpson, Barbara A. Whitney, Dean C. Hines +6

Massive young stellar objects (YSOs), like low-mass YSOs, are thought to be surrounded by optically thick envelopes and/or discs and are observed to have associated regions that pr…

Three New Galactic Center X-ray Sources Identified with Near-Infrared Spectroscopy

Curtis DeWitt, Reba M. Bandyopadhyay, Stephen S. Eikenberry +5

We have conducted a near-infrared spectroscopic survey of 47 candidate counterparts to X-ray sources discovered by the Chandra X-ray Observatory near the Galactic Center (GC). Thou…

The Top Ten Spitzer YSOs in 30 Doradus

Nolan R. Walborn, Rodolfo H. Barba, Marta M. Sewilo

The most luminous Spitzer point sources in the 30 Doradus triggered second generation are investigated coherently in the 3-8 micron region. Remarkable diversity and complexity in t…

The Luminosities of Protostars in the Spitzer c2d and Gould Belt Legacy Clouds

Michael M. Dunham, Hector G. Arce, Lori E. Allen +14

Motivated by the long-standing "luminosity problem" in low-mass star formation whereby protostars are underluminous compared to theoretical expectations, we identify 230 protostars…
