Working Group Report on the "TeV Particle Astrophysics and Physics Beyond the Standard Model"
Ivone F. M. Albuquerque, Sergio Palomares-Ruiz, Tom Weiler
This working group focused mainly on the complementarity among particle physics and astrophysics. The analysis of data from both fields will better constrain theoretical models. Mu…
TeV gamma-rays and neutrinos from photo-disintegration of nuclei in Cygnus OB2
Luis A. Anchordoqui, John F. Beacom, Haim Goldberg +2
TeV gamma-rays may provide significant information about high energy astrophysical accelerators. Such gamma-rays can result from the photo-de-excitation of PeV nuclei after their p…
TeV gamma-rays from photo-disintegration/de-excitation of cosmic-ray nuclei
Luis A. Anchordoqui, John F. Beacom, Haim Goldberg +2
It is commonly assumed that high-energy gamma-rays are made via either purely electromagnetic processes or the hadronic process of pion production, followed by decay. We investigat…
Found: The missing blue opacity in atmosphere models of cool hydrogen white dwarfs
P. M. Kowalski, D. Saumon
We investigate the importance of the far red wing of the Lyman line of hydrogen in the atmospheres of cool white dwarfs of pure hydrogen composition. We find that this absorpt…
An Observational Study of Tidal Synchronization in Solar-Type Binary Stars in the Open Clusters M35 and M34
Soren Meibom, Robert D. Mathieu, Keivan G. Stassun
We present rotation periods for the solar-type primary stars in 13 close (a~< 5 AU) single-lined spectroscopic binaries with known orbital periods (P) and eccentricities (e). All b…
Silicon Monoxide Observations Reveal a Cluster of Hidden Compact Outflows in the OMC1 South Region
Luis A. Zapata, Paul T. P. Ho, Luis F. Rodriguez +3
We present high angular resolution () SiO J=54; line observations of the OMC1S region in the Orion Nebula made using the Submillimeter…
V1647 Ori: The X-ray Evolution of a Pre-main Sequence Accretion Burst
J. H. Kastner, M. Richmond, N. Grosso +6
We present Chandra X-ray Observatory monitoring observations of the recent accretion outburst displayed by the pre-main sequence (pre-MS) star V1647 Ori. The X-ray observations wer…
A Simultaneous Optical and X-ray Variability Study of the Orion Nebula Cluster. I. Incidence of Time-Correlated X-ray/Optical Variations
Keivan G. Stassun, M. van den Berg, Eric Feigelson +1
We present a database of time-series photometry of the Orion Nebula Cluster obtained with two ground-based telescopes at different longitudes to provide simultaneous coverag…
Phantom Dark Energy Models with Negative Kinetic Term
Jens Kujat, Robert J. Scherrer, A. A. Sen
We examine phantom dark energy models derived from a scalar field with a negative kinetic term for which V(phi) approaches infinity asymptotically. All such models can be divided i…
Long gamma-ray bursts and core-collapse supernovae have different environments
A. S. Fruchter, A. J. Levan, L. Strolger +30
When massive stars exhaust their fuel they collapse and often produce the extraordinarily bright explosions known as core-collapse supernovae. On occasion, this stellar collapse al…
Cloud fragmentation and proplyd-like features in HII regions imaged by HST
Orsola De Marco, C. R. O'Dell, Pamela Gelfond +2
We have analyzed HST ACS and WFPC2 new and archival images of eight HII regions to look for new proto-planetary disks (proplyds) similar to those found in the Orion Nebula. We find…
Measurement of Ω_m, Ω_Λ from a blind analysis of Type Ia supernovae with CMAGIC: Using color information to verify the acceleration of the Universe
A. Conley, G. Goldhaber, L. Wang +26
We present measurements of Ω_m and Ω_Λ from a blind analysis of 21 high-redshift supernovae using a new technique (CMAGIC) for fitting the multi-color lightcurves of Type Ia supern…
A deep wide-field optical survey in the young open cluster Collinder 359
N. Lodieu, J. Bouvier, D. J. James +4
We present the first deep, optical, wide-field imaging survey of the young open cluster Collinder 359, complemented by near-infrared follow-up observations. This study is part of a…
