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...
X-ray observations of classical and recurrent novae in Outburst
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...
