Onset of Cosmic Reionization: Evidence of An Ionized Bubble Merely 680 Myrs after the Big Bang
V. Tilvi, S. Malhotra, J. E. Rhoads +14
While most of the inter-galactic medium (IGM) today is permeated by ionized hydrogen, it was largely filled with neutral hydrogen for the first 700 million years after the Big Bang…
Relativistic Outflows in two quasars in the Chandra Deep Field South
Z. Y. Zheng, J. X. Wang
In this paper, we provide new 1 Ms ACIS spectra of two quasars in the Chandra Deep Field South (CDF-S), which were previously reported to show strong and extremely bluesh…
Chandra X-ray Sources in the LALA Cetus Field
J. X. Wang, Z. Y. Zheng, S. Malhotra +4
The 174 ks Chandra Advanced CCD Imaging Spectrometer exposure of the Large Area Lyman Alpha Survey (LALA) Cetus field is the second of the two deep Chandra images on LALA fields. I…
On the X-ray Baldwin effect for narrow Fe Kalpha emission line
P. Jiang, J. X. Wang, T. G. Wang
Most Active Galactic Nuclei (AGN) exhibit a narrow Fe Kalpha line at ~ 6.4 keV in the X-ray spectra, due to the fluorescent emission from cold material far from the inner accretion…
An overdensity of galaxies at z=5.9 +/-0.2 in the Ultra Deep Field confirmed using the ACS grism
S. Malhotra, J. E. Rhoads, N. Pirzkal +17
We present grism spectra taken with the Advanced Camera for Surveys to identify 29 red sources with (i'-z') > 0.9 in the Hubble Ultra Deep Field (HUDF). Of these 23 are found to be…
