Multimessenger astronomy with pulsar timing and X-ray observations of massive black hole binaries
Black hole physics – Accretion, accretion discs – Gravitational waves –pulsars: general – X-rays: general
2011/10/9
We demonstrate that very massive (>10^8\msun), cosmologically nearby (z<1) black hole binaries (MBHBs), which are primary targets for ongoing and upcoming pulsar timing arrays (PTAs), are particularly...
Deep Multiwaveband Observations of the Jets of 0208-512 and 1202-262
Observations Jets 0208-512 1202-262
2011/10/8
We present deep {\it HST, Chandra, VLA} and {\it ATCA} images of the jets of PKS 0208--512 and PKS 1202--262, which were found in a {\it Chandra} survey of a flux-limited sample of flat-spectrum radio...
Panchromatic Observations of SN 2011dh Point to a Compact Progenitor Star
Panchromatic Observations Compact Progenitor Star
2011/9/30
We report the discovery and detailed monitoring of X-ray emission associated with the Type IIb SN 2011dh using data from the Swift and Chandra satellites, placing it among the best studied X-ray super...

VERITAS Observations Unusual Extragalactic Transient Swift
2011/9/30
We report on very-high-energy ($>$100 GeV) gamma-ray observations of Swift J164449.3+573451, an unusual transient object first detected by the {\it Swift} Observatory and later detected by multiple ra...

Rosat x-ray observations of central galactic starbursts
GALAXIES x-ray observations central galactic starbursts
2009/6/4
We present spatial and spectral results of ROSAT observations of two galax-ies: NGC 4569 and NGC 4303. Both objects are members of the Virgo Cluster andhave nearby smaller companions with which they h...
Needs and requirements for future x-ray observations of hot galactic halos
HALOS X-RAYS JETS AND OUTFLOWS
2009/6/4
Galaxies are key objects for the study of cosmology, the life cycle of matter,and stellar evolution. X-ray observations have given us a new key window intothese building blocks of the Universe, that a...
