Search for Primordial Black Holes with SGARFACE
M. Schroedter, F. Krennrich, S. LeBohec +7
The Short GAmma Ray Front Air Cherenkov Experiment (SGARFACE) uses the Whipple 10 m telescope to search for bursts of rays. SGARFACE is sensitive to bursts with duration from a…
A census of molecular hydrogen outflows and their sources along the Orion A molecular ridge: characteristics and overall distribution
C. J. Davis, D. Froebrich, T. Stanke +9
We present wide-field near-IR images of Orion A. K and H2 1-0S(1) images of a contiguous 8 sqr degree region are compared to photometry from Spitzer and dust-continuum maps obtaine…
The June 2008 flare of Markarian 421 from optical to TeV energies
The Agile Collaboration, Webt Collaboration, Magic Collaboration +2
We present optical, X-ray, high energy ( GeV) and very high energy ( GeV; VHE) observations of the high-frequency peaked blazar Mrk 421 taken betwee…
Discovery of Very High-Energy Gamma-Ray Radiation from the BL Lac 1ES 0806+524
VERITAS Collaboration, V. Acciari, E. Aliu +90
The high-frequency-peaked BL-Lacertae object \objectname{1ES 0806+524}, at redshift z=0.138, was observed in the very-high-energy (VHE) gamma-ray regime by VERITAS between November…
NEAR-IR Spectroscopy of Young Stars in the Braid Nebula Star Formation Region in Cygnus Ob7
Colin Aspin, Tracy L. Beck, Tae-Soo Pyo +8
We present 1.4 to 2.5 um integral field spectroscopy of 16 stars in the Braid Nebula star formation region in Cygnus OB7. These data forms one aspect of a large-scale multi-wavelen…
Investigations of the magnetospheric plasma distribution in the vicinity of a pulsar - I Basic formulation
John Mc Donald, Andrew Shearer
The magnetospheric plasma distribution in the vicinity of a pulsar at various inclination angles is investigated using a new relativistic, parallel 3D Particle-In-Cell (PIC) code D…
VERITAS Discovery of >200GeV Gamma-ray Emission from the Intermediate-frequency-peaked BL Lac Object W Comae
VERITAS Collaboration, V. A. Acciari, E. Aliu +80
We report the detection of very high-energy gamma-ray emission from the intermediate-frequency-peaked BL Lacertae object W Comae (z=0.102) by VERITAS. The source was observed betwe…
Optical Observations of PSR J0205+6449
A. Shearer, V. V. Neustroev
PSR J0205+6449 is a X-ray and radio pulsar in supernova remnant 3C 58. We report on observations of the central region of 3C 58 using the 4.2-m William Herschel Telescope with the…
Simultaneous Absolute Timing of the Crab Pulsar at Radio and Optical Wavelengths
T. Oosterbroek, I. Cognard, A. Golden +7
The Crab pulsar emits across a large part of the electromagnetic spectrum. Determining the time delay between the emission at different wavelengths will allow to better constrain t…
A Mini-survey of Ultracool Dwarfs at 4.9 GHz
A. Antonova, J. G. Doyle, G. Hallinan +2
A selection of ultracool dwarfs are known to be radio active, with both gyrosynchrotron emission and the electron cyclotron maser instability being given as likely emission mechani…
Confirmation of the Electron Cyclotron Maser Instability as the Dominant Source of Radio Emission from Very Low Mass Stars and Brown Dwarfs
G. Hallinan, A. Antonova, J. G. Doyle +3
We report on radio observations of the M8.5 dwarf LSR J1835+3259 and the L3.5 dwarf 2MASS J00361617+1821104, which provide the strongest evidence to date that the electron cyclotro…
Reference-less detection, astrometry, and photometry of faint companions with adaptive optics
Szymon Gladysz, Julian C. Christou
We propose a complete framework for the detection, astrometry, and photometry of faint companions from a sequence of adaptive optics corrected short exposures. The algorithms explo…
Cyclic brightening in the short-period WZ Sge-type cataclysmic variable SDSS J080434.20+510349.2
S. V. Zharikov, G. H. Tovmassian, V. V. Neustroev +8
We have observed a new cataclysmic variable (CV) SDSS J080434.20+510349.2 and study the origin of a long-term variability found in its light curve. Multi-longitude time-resolved ph…
VERITAS Observations of the gamma-Ray Binary LS I +61 303
V. A. Acciari, M. Beilicke, G. Blaylock +74
LS I +61 303 is one of only a few high-mass X-ray binaries currently detected at high significance in very high energy gamma-rays. The system was observed over several orbital cycl…

V. A. Acciari, M. Beilicke, G. Blaylock +74
The multiwavelength observation of the nearby radio galaxy M87 provides a unique opportunity to study in detail processes occurring in Active Galactic Nuclei from radio waves to Te…
A Search for Dark Matter Annihilation with the Whipple 10m Telescope
