We constrain parity-violating interactions to the surface of last scattering using spectra from the QUaD experiment's second and third seasons of observations by searching for a po…
The X-ray luminosity function of AGN at z~3
James Aird, Kirpal Nandra, Antonis Georgakakis +3
We combine Lyman-break colour selection with ultradeep (> 200 ks) Chandra X-ray imaging over a survey area of ~0.35 deg^2 to select high redshift AGN. Applying careful corrections…
Rotational quasi periodicities and the Sun - heliosphere connection
J. K. Lawrence, A. C. Cadavid, A. Ruzmaikin
Mutual quasi-periodicities near the solar-rotation period appear in time series based on the Earth's magnetic field, the interplanetary magnetic field, and signed solar-magnetic fi…

X-ray properties of protostars in the Orion Nebula
L. Prisinzano, G. Micela, E. Flaccomio +8
The origin and evolution of the X-rays in very young stellar objects (YSOs) are not yet well understood since it is very hard to observe YSOs in the protostellar phase. We study th…

We present the first mid-infrared (5.5-14.5 micron) spectrum of a highly magnetic cataclysmic variable, EF Eridani, obtained with the Infrared Spectrograph on the Spitzer Space Tel…
A Planetary Mass Companion to the K0 Giant HD 17092
A. Niedzielski, M. Konacki, A. Wolszczan +6
We report the discovery of a substellar-mass companion to the K0-giant HD 17092 with the Hobby-Eberly Telescope. In the absence of any correlation of the observed 360-day periodici…
Automated selection and characterization of emission-line sources in ACS WFC grism data
Gerhardt R. Meurer, Z. I. Tsvetanov, C. Gronwall +10
We present complimentary techniques to find emission-line targets and measure their properties in a semi-automated fashion from grism observations obtained with the Advanced Camera…
Profiles of heating in turbulent coronal magnetic loops
E. Buchlin, P. J. Cargill, S. J. Bradshaw +1
Context: The location of coronal heating in magnetic loops has been the subject of a long-lasting controversy: does it occur mostly at the loop footpoints, at the top, is it random…
A Search for Deep Impact's Large Particle Ejecta
Michael S. Kelley, William T. Reach, Charles E. Woodward
The Deep Impact encounter with the nucleus of 9P/Tempel ejected small grains (a <~ 10 micron) into the comet's coma, evidenced by thermal emission from small dust grains at mid-inf…
CO line emission from Lyman Break Galaxies. Cosmological simulations and predictions for ALMA
T. R. Greve, J. Sommer-Larsen
[Abridged] The detection of the rotational lines of CO in proto-galaxies in the early Universe provides one of the most promising ways of probing the fundamental physical propertie…
A Time Delay for the Largest Gravitationally Lensed Quasar: SDSS J1004+4112

We present 426 epochs of optical monitoring data spanning 1000 days from December 2003 to June 2006 for the gravitationally lensed quasar SDSS J1004+4112. The time delay between th…
Galaxy orbits and the intracluster gas temperature in clusters
Latchezar Benatov, Ken Rines, Priyamvada Natarajan +2
In this paper we examine how well galaxies and intra-cluster gas trace the gravitational potential of clusters. Utilizing mass profiles derived from gravitational lensing and X-ray…
Spitzer/IRAC and ISOCAM/CVF insights on the origin of the Near to Mid-IR Galactic diffuse emission
N. Flagey, F. Boulanger, L. Verstraete +3
We measure IRAC colors of extended emission in several fields covering a range of Galactic latitudes and longitudes outside of star forming regions. We determine the nature of the…

Ammonia in Infrared Dark Clouds
Thushara Pillai, Friedrich Wyrowski, Sean J. Carey +1
Infrared Dark Clouds appear to be the long sought population of cold and dense aggregations with the potential of harbouring the earliest stages of massive star formation. Up to no…
