The Origin of Parsec-Scale Gaseous and Stellar Disks in the Galactic Center and AGNs

F. Yusef-Zadeh, M. Wardle

The Galactic center stellar disk and the circumnuclear ring provide a unique opportunity to study in detail the dynamics and physical conditions of distant molecular disks in the n…

Near-infrared and Millimeter-wavelength Observations of Mol 160: A Massive Young Protostellar Core

Grace Wolf-Chase, Michael Smutko

We have discovered two compact sources of shocked H2 2.12-micron emission coincident with Mol 160 (IRAS 23385+6053), a massive star-forming core thought to be a precursor to an ult…

On the Rarity of X-Ray Binaries with Naked Helium Donors

T. Linden, F. Valsecchi, V. Kalogera

The paucity of known High-Mass X-Ray Binaries (HMXB) with naked He donor stars (hereafter He star) in the Galaxy has been noted over the years as a surprising fact, given the signi…

Missing Black Holes Unveil The Supernova Explosion Mechanism

K. Belczynski, G. Wiktorowicz, C. Fryer +2

It is firmly established that the stellar mass distribution is smooth, covering the range 0.1-100 Msun. It is to be expected that the masses of the ensuing compact remnants correla…

HST Observations of the Stellar Distribution Near Sgr A*

F. Yusef-Zadeh, H. Bushouse, M. Wardle

We present HST/NICMOS data to study the surface brightness distribution of stellar light within the inner 10" of Sgr A* at 1.4, 1.7 and 1.9 microns. We use these data to independen…

The Magnetic Field in Taurus Probed by Infrared Polarization

Nicholas L. Chapman, Paul F. Goldsmith, Jorge L. Pineda +3

We present maps of the plane-of-sky magnetic field within two regions of the Taurus molecular cloud: one in the dense core L1495/B213 filament, the other in a diffuse region to the…

Line derived infrared extinction towards the Galactic Center

Tobias K. Fritz, Stefan Gillessen, Katie Dodds-Eden +7

We derive the extinction curve towards the Galactic Center from 1 to 19 micron. We use hydrogen emission lines of the minispiral observed by ISO-SWS and SINFONI. The extinction fre…

Formation of Massive Black Holes in Dense Star Clusters. II. IMF and Primordial Mass Segregation

Sanghamitra Goswami, Stefan Umbreit, Matt Bierbaum +1

A promising mechanism to form intermediate-mass black holes (IMBHs) is the runaway merger in dense star clusters, where main-sequence stars collide and form a very massive star (VM…

The Local Leo Cold Cloud and New Limits on a Local Hot Bubble

J. E. G. Peek, Carl Heiles, Kathryn M. G. Peek +2

We present a multi-wavelength study of the local Leo cold cloud (LLCC), a very nearby, very cold cloud in the interstellar medium. Through stellar absorption studies we find that t…

Magnetic Field Structure around Low-Mass Class 0 Protostars: B335, L1527 and IC348-SMM2

J. A. Davidson, G. Novak, T. G. Matthews +6

We report new 350 micron polarization observations of the thermal dust emission from the cores surrounding the low-mass, Class 0 YSOs L1527, IC348-SMM2 and B335. We have inferred m…

Methanol Maser Emission from Galactic Center Sources with Excess 4.5 μm Emission

Edward T. Chambers, Farhad Yusef-Zadeh, Doug Roberts

We present a study of signatures of on-going star formation in a sample of protostellar objects with enhanced 4.5 μm emission ('green' sources) near the Galactic center. To underst…

A Constraint on the Organization of the Galactic Center Magnetic Field Using Faraday Rotation

C. J. Law, M. A. Brentjens, G. Novak

We present new 6 and 20 cm Very Large Array (VLA) observations of polarized continuum emission of roughly 0.5 square degrees of the Galactic center (GC) region. The 6 cm observatio…
