Superorbital variability in the quiescent black hole X-ray transient A0620-00
Enzo A. Saavedra, Roi Alonso, Teo Muñoz-Darias +10
Quiescent black hole low-mass X-ray binaries provide a key setting for probing accretion physics at low luminosities. A0620-00, the archetypal system in this class, has remained in…
Panning for gold, but finding helium: discovery of the ultra-stripped supernova SN2019wxt from gravitational-wave follow-up observations
I. Agudo, L. Amati, T. An +96
We present the results from multi-wavelength observations of a transient discovered during the follow-up of S191213g, a gravitational wave (GW) event reported by the LIGO-Virgo Col…
Transient-optimised real-bogus classification with Bayesian Convolutional Neural Networks -- sifting the GOTO candidate stream
T. L. Killestein, J. Lyman, D. Steeghs +45
Large-scale sky surveys have played a transformative role in our understanding of astrophysical transients, only made possible by increasingly powerful machine learning-based filte…
Einstein@Home Discovery of the Gamma-ray Millisecond Pulsar PSR J2039-5617 Confirms Its Predicted Redback Nature
C. J. Clark, L. Nieder, G. Voisin +19
The Fermi Large Area Telescope gamma-ray source 3FGL J2039.65618 contains a periodic optical and X-ray source that was predicted to be a "redback" millisecond pulsar (MSP) binar…
Searching for Electromagnetic Counterparts to Gravitational-wave Merger Events with the Prototype Gravitational-wave Optical Transient Observer (GOTO-4)
B. P. Gompertz, R. Cutter, D. Steeghs +49
We report the results of optical follow-up observations of 29 gravitational-wave triggers during the first half of the LIGO-Virgo Collaboration (LVC) O3 run with the Gravitational-…
The Changing-look Optical Wind of the Flaring X-ray Transient Swift J1858.6-0814
T. Muñoz-Darias, M. Armas Padilla, F. Jiménez-Ibarra +15
We present the discovery of an optical accretion disk wind in the X-ray transient Swift J1858.6-0814. Our 90-spectrum data set, taken with the 10.4m GTC telescope over 8 different…
Hard-state accretion disk winds from black holes: the revealing case of MAXI J1820+070
T. Muñoz-Darias, F. Jiménez-Ibarra, G. Panizo-Espinar +16
We report on a detailed optical spectroscopic follow-up of the black hole transient MAXI J1820+070 (ASASSN-18ey). The observations cover the main part of the X-ray binary outburst,…
The long-term optical evolution of the black hole candidate MAXI J1659-152
Jesus M. Corral-Santana, Manuel A. P. Torres, Tariq Shahbaz +13
We present 5 years of optical and infrared data of the black hole candidate MAXI J1659-152 covering its 2010 outburst, decay and quiescence. Combining optical data taken during the…
Swift and SALT observations of the Multiple Outbursts of MAXI J1957+032
D. Mata Sánchez, P. A. Charles, M. Armas Padilla +4
The new recurrent X-ray transient MAXI J1957+032 has had four X-ray outbursts within 16 months, all very briefly detected (lasting <5 days). During the most recent event (Sep/Oct 2…
The donor of Aquila X-1 revealed by high angular resolution near-infrared spectroscopy
D. Mata Sánchez, T. Muñoz-Darias, J. Casares +1
The low mass X-ray binary Aquila X-1 is one of the most active neutron star X-ray transients. Despite it has a relatively bright quiescent optical counterpart, the detection of its…
Swift J1357.2-0933: a massive black hole in the Galactic thick disc
Daniel Mata Sánchez, Teo Munoz-Darias, Jorge Casares +2
Swift J1357.2-0933 is one of the shortest orbital period black hole X-ray transients (BHTs). It exhibited deep optical dips together with an extremely broad H line during outbur…
Mass constraints to Sco X-1 from Bowen flourescence and deep near-infrared spectroscopy
D. Mata Sánchez, T. Muñoz-Darias, J. Casares +3
More than 50 years after the dawn of X-ray astronomy, the dynamical parameters of the prototypical X-ray binary Sco X-1 are still unknown. We combine a Monte Carlo analysis, which…
