Hard X-ray (≥ 10 keV) observations of active galactic nuclei (AGNs) can shed light on some
of the most obscured episodes of accretion onto supermassive black holes. The 70-month …

The majority of the accreting supermassive black holes in the Universe are obscured by
large columns of gas and dust,,. The location and evolution of this obscuring material have …

ABSTRACT To date, the Burst Alert Telescope (BAT) onboard Swift has detected∼ 1000
gamma-ray bursts (GRBs), of which∼ 360 GRBs have redshift measurements, ranging from …

With the advent of more sensitive all-sky instruments, the transient universe is being probed
in greater depth than ever before. Taking advantage of available resources, we have …

We investigate whether the emission of neutrinos observed in 2014–2015 from the direction
of the blazar TXS 0506+ 056 can be accommodated with leptohadronic multiwavelength …

Abstract Swift J0243. 6+ 6124 is a newly discovered Galactic Be/X-ray binary, revealed in
late 2017 September in a giant outburst with a peak luminosity of 2× 10 39 (d/7 kpc) 2 erg s …

We present radio and γ-ray observations, which, along with concurrent X-ray observations,
reveal that the binary millisecond pulsar (MSP)/low-mass X-ray binary transition system PSR …

ABSTRACT MAXI J1820+ 070 (optical counterpart ASASSN-18ey) is a black hole candidate
discovered through its recent very bright outburst. The low extinction column and long …

The IceCube report of as~ 3.5 excess of 13± 5 neutrino events in the direction of the
blazar TXS 0506+ 056 in 2014–2015 and the 2017 detection of a high-energy neutrino …

On 2021 August 8, the recurrent nova RS Ophiuchi (RS Oph) erupted again, after an interval
of 15.5 yr. Regular monitoring by the Neil Gehrels Swift Observatory began promptly, on …
