Wide Field Multiband Imaging of Low Redshift Quasar Environments
Jennifer E. Scott, Alireza Rafiee, Jill Bechtold +3
We present photometry of the large scale environments of a sample of twelve broad line AGN with from deep images in the SDSS , , , and filters taken…
Confronting Cosmology and New Physics with Fundamental Constants
Rodger I. Thompson
The values of the fundamental constants such as , the proton to electron mass ratio and , the fine structure constant, are sensitive to the product $\sqrt{ζ_x^2(w+1)…
On the connection between the intergalactic medium and galaxies: The HI-galaxy cross-correlation at z < 1
Nicolas Tejos, Simon L. Morris, Charles W. Finn +9
We present a new optical spectroscopic survey of 1777 'star-forming' ('SF') and 366 'non-star-forming' ('non-SF') galaxies at redshifts z < 1 (2143 in total), 22 AGN and 423 stars,…
A high molecular fraction in a sub-damped absorber at z=0.56
Neil H. M. Crighton, Jill Bechtold, Robert F. Carswell +8
Measuring rest-frame ultraviolet rotational transitions from the Lyman and Werner bands in absorption against a bright background continuum is one of the few ways to directly measu…
Deep Chandra X-ray Imaging of a Nearby Radio Galaxy 4C+29.30: X-ray/Radio Connection
Aneta Siemiginowska, Łukasz Stawarz, Chi C. Cheung +8
We report results from our deep Chandra X-ray observations of a nearby radio galaxy, 4C+29.30 (z=0.0647). The Chandra image resolves structures on sub-arcsec to arcsec scales, reve…
High redshift X-ray cooling-core cluster associated with the luminous radio loud quasar 3C186
Aneta Siemiginowska, D. J. Burke, Thomas L. Aldcroft +5
We present the first results from a new, deep (200ks) Chandra observation of the X-ray luminous galaxy cluster surrounding the powerful (L ~10^47 erg/s), high-redshift (z=1.067), c…
