    Multiwavelength Observations of the Black Hole Transient XTE J1752–223 during Its 2010 Outburst Decay
    Galactic black hole transients show many interesting phenomena during outburst decays. We present simultaneous X-ray (RXTE, Swift, and INTEGRAL), and optical...

    Multiwavelength Study of the Bright X-Ray Source Population in the Interacting Galaxies NGC 5774/NGC 5775
    A few nearby interacting galaxies are known that host elevated numbers of ultraluminous X-ray sources. Here we report the results of a multiwavelength study of...

    NICER observations reveal that the X-ray transient MAXI J1348-630 is a black hole X-ray binary
    We studied the outburst evolution and timing properties of the recently discovered X-ray transient MAXI J1348-630 as observed with NICER. We produced the...

    Observational constraints on the powering mechanism of transient relativistic jets
    We revisit the paradigm of the dependence of jet power on black hole (BH) spin in accreting BH systems. In a previous paper, we showed that the luminosity of...
