An XMM-Newton Spectral and Timing Study of IGR J16207-5129: An Obscured and Non-Pulsating HMXB
John A. Tomsick, Sylvain Chaty, Jerome Rodriguez +3
We report on a 12 hr XMM-Newton observation of the supergiant High-Mass X-ray Binary IGR J16207-5129. This is only the second soft X-ray (0.4-15 keV, in this case) study of the sou…
Fermi LAT Observations of the Vela Pulsar
A. A. Abdo
The Vela pulsar is the brightest persistent source in the GeV sky and thus is the traditional first target for new gamma-ray observatories. We report here on initial Fermi Large Ar…
Physical and chemical conditions in methanol maser selected hot-cores and UCHII regions
C. R. Purcell, S. N. Longmore, M. G. Burton +4
We present the results of a targeted 3-mm spectral line survey towards the eighty-three 6.67 GHz methanol maser selected star forming clumps observed by Purcell et al. 2006. In add…
Redshifts and lens profile for the double quasar QJ 0158-4325
C. Faure, T. Anguita, A. Eigenbrod +5
We report on the redshift of the lensing galaxy and of the quasar QJ 0158-4325 and on the lens model of the system. A deep VLT/FORS2 spectrum and HST/NICMOS-F160W images are deconv…
A Surprisingly High Pair Fraction for Extremely Massive Galaxies at z ~ 3 in the GOODS NICMOS Survey
Asa F. L. Bluck, Christopher J. Conselice, Rychard J. Bouwens +4
We calculate the major pair fraction and derive the major merger fraction and rate for 82 massive () galaxies at utilising deep HST NICMOS d…
The spatial clustering of X-ray selected AGN in the XMM-COSMOS field
R. Gilli, G. Zamorani, T. Miyaji +70
We study the spatial clustering of 538 X-ray selected AGN in the 2 deg^2 XMM-COSMOS field that are spectroscopically identified to I_{AB}<23 and span the redshift range z=0.2-3.0.…
