The inner∼ 200 pc region of the Galaxy contains a 4 million M⊙ supermassive black hole
(SMBH), significant quantities of molecular gas, and star formation and cosmic-ray energy …

Low-frequency quasiperiodic oscillations (LFQPOs) are commonly found in black hole X-ray
binaries, and their origin is still under debate. The properties of LFQPOs at high energies …

INTEGRAL is an ESA mission in fundamental astrophysics that was launched in October
2002. It has been in orbit for over 18 years, during which it has been observing the high …

We perform the first systematic search of all NICER archival observations of black hole (and
candidate) low-mass X-ray binaries for signatures of reverberation. Reverberation lags …

We report new radio observations of a sample of 36 neutron star (NS) X-ray binaries, more
than doubling the sample in the literature observed at current-day sensitivities. These …

We present the radio and X-ray monitoring campaign of the 2019/2020 outburst of MAXI
J1348–630, a new black hole X-ray binary (BH XRB) discovered in 2019 January. We …

We present deep X-ray and radio observations of the fast blue optical transient (FBOT) AT
2020xnd/ZTF 20acigmel at z= 0.2433 from 13 days to 269 days after explosion. AT 2020xnd …

Radio observations of tidal disruption events (TDEs)—when a star is tidally disrupted by a
supermassive black hole (SMBH)—provide a unique laboratory for studying outflows in the …

We present multiwavelength fast timing observations of the black hole X-ray binary MAXI
J1820+ 070 (ASASSN-18ey), taken with the Karl G. Jansky Very Large Array (VLA) …

ABSTRACT We analyse a Neutron Star Interior Composition Explorer observation of the
black hole X-ray binary MAXI J1820+ 070 during a transition from type-C to type-B quasi …
