Quasi-simultaneous Integral, Swift, And Nustar Observations Of The New X-ray Clocked Burster 1rxsj180408.9-342058
M. Fiocchi, A. Bazzano, G. Bruni +4
We report the quasi-simultaneous INTEGRAL, SWIFT, and NuSTAR observations showing spectral state transitions in the neutron star low mass X-ray binary 1RXS J180408.9-342058 during…
The transitional gap transient AT 2018hso: new insights on the luminous red nova phenomenon
Y-Z. Cai, A. Pastorello, M. Fraser +20
Aims: AT 2018hso is a new transient showing transitional properties between those of LRNe and the class of intermediate luminosity red transients (ILRTs) similar to SN 2008S. Throu…
Optical follow-up of the tidal disruption event iPTF16fnl: new insights from X-shooter observations
F. Onori, G. Cannizzaro, P. G. Jonker +11
We present the results from Nordic Optical Telescope and X-shooter follow-up campaigns of the tidal disruption event (TDE) iPTF16fnl, covering the first 100 days after the tr…
The Evolution of Luminous Red Nova AT 2017jfs in NGC 4470
A. Pastorello, T. -W. Chen, Y. -Z. Cai +43
We present the results of our photometric and spectroscopic follow-up of the intermediate-luminosity optical transient AT 2017jfs. At peak, the object reaches an absolute magnitude…
Pulsating in unison at optical and X-ray energies: simultaneous high-time resolution observations of the transitional millisecond pulsar PSR J1023+0038
A. Papitto, F. Ambrosino, L. Stella +22
PSR J1023+0038 is the first millisecond pulsar discovered to pulsate in the visible band; such a detection took place when the pulsar was surrounded by an accretion disk and also s…
Evidence for rapid disk formation and reprocessing in the X-ray bright tidal disruption event AT 2018fyk
T. Wevers, D. R. Pasham, S. van Velzen +15
We present optical spectroscopic and Swift UVOT/XRT observations of the X-ray and UV/optical bright tidal disruption event (TDE) AT 2018fyk/ASASSN-18ul discovered by ASAS-SN. The S…
The spectral evolution of AT 2018dyb and the presence of metal lines in tidal disruption events
Giorgos Leloudas, Lixin Dai, Iair Arcavi +29
We present light curves and spectra of the tidal disruption event (TDE) ASASSN-18pg / AT 2018dyb spanning a period of one year. The event shows a plethora of strong emission lines,…
Black hole masses of tidal disruption event host galaxies II
Thomas Wevers, Nicholas C. Stone, Sjoert van Velzen +5
We present new medium resolution, optical long-slit spectra of a sample of 6 UV/optical and 15 X-ray selected tidal disruption event candidate host galaxies. We measure emission li…
Discovery and Follow-up of the Unusual Nuclear Transient OGLE17aaj
M. Gromadzki, A. Hamanowicz, L. Wyrzykowski +31
We report on the discovery and follow-up of a peculiar transient, OGLE17aaj, which occurred in the nucleus of a weakly active galaxy. We investigate whether it can be interpreted a…
