A Chandra Observation of 3C 288—Reheating ohe Cool Core of a 3 Kev Cluster from a Nuclear Outburst at Z = 0.246
(IOP Publishing, 2010)We present results from a 42 ks Chandra/ACIS-S observation of the transitional FR I/FR II radio galaxy 3C 288 at z = 0.246. We detect ~3 keV gas extending to a radius of ~0.5 Mpc with a 0.5-2.0 keV luminosity of 6.6 × 1043 ... -
The Distortion of the Cosmic Microwave Background Spectrum Due to Intergalactic Dust
(American Astronomical Society, 2016)Infrared emission from intergalactic dust might compromise the ability of future experiments to detect subtle spectral distortions in the Cosmic Microwave Background (CMB) from the early Universe. We provide the first ... -
GRB 130606A as a Probe of the Intergalactic Medium and the Interstellar Medium in a Star-forming Galaxy in the First Gyr After the Big Bang
(IOP Publishing, 2013)We present high signal-to-noise ratio Gemini and MMT spectroscopy of the optical afterglow of the gamma-ray burst (GRB) 130606A at redshift z=5.913, discovered by Swift. This is the first high-redshift GRB afterglow to ... -
Limits on Intergalactic Dust During Reionization
(American Astronomical Society, 2016)In this Letter, we constrain the dust-to-gas ratio in the intergalactic medium (IGM) at high redshifts. We employ models for dust in the local Universe to contrain the dust-to-gas ratio during the epoch of reionization at ... -
No Precise Localization for Frb 150418: Claimed Radio Transient Is Agn Variability
(American Astronomical Society, 2016)Keane et al. have recently claimed to have obtained the first precise localization for a Fast Radio Burst (FRB) thanks to the identification of a contemporaneous fading slow (∼week-timescale) radio transient. They use this ...
