A Low Frequency Survey of Giant Pulses from the Crab Pulsar
T. Eftekhari, K. Stovall, J. Dowell +2
We present a large survey of giant pulses from the Crab Pulsar as observed with the first station of the Long Wavelength Array. Automated methods for detecting giant pulses at low…
HST imaging of the dusty filaments and nucleus swirl in NGC4696 at the centre of the Centaurus Cluster
A. C. Fabian, S. A. Walker, H. R. Russell +14
Narrow-band HST imaging has resolved the detailed internal structure of the 10 kpc diameter H alpha+[NII] emission line nebulosity in NGC4696, the central galaxy in the nearby Cent…
Binary Black Holes, Gas Sloshing, and Cold Fronts in the X-ray Halo Hosting 4C+37.11
Felipe Andrade-Santos, Akos Bogdan, Roger W. Romani +5
We analyzed deep ACIS-I exposures of the cluster-scale X-ray halo surrounding the radio source 4C+37.11. This remarkable system hosts the closest resolved pair of super-m…
Deep Chandra study of the truncated cool core of the Ophiuchus cluster
N. Werner, I. Zhuravleva, R. E. A. Canning +7
We present the results of a deep (280 ks) Chandra observation of the Ophiuchus cluster, the second-brightest galaxy cluster in the X-ray sky. The cluster hosts a truncated cool cor…
Compact Symmetric Objects and Supermassive Binary Black Holes in the VLBA Imaging and Polarimetry Survey
S. E. Tremblay, G. B. Taylor, A. A. Ortiz +3
We present multi-frequency Very Long Baseline Array (VLBA) follow-up observations of VLBA Imaging and Polarimetry Survey sources identified as likely compact symmetric objects (CSO…
