Accretion disc reverberation mapping of the quasar 3C 273

James P. Thorne, Hermine Landt, Jiamu Huang +5

We present accretion disc size measurements for the well-known quasar 3C 273 using reverberation mapping (RM) performed on high-cadence light-curves in seven optical filters collec…

AGN STORM 2: II. Ultraviolet Observations of Mrk817 with the Cosmic Origins Spectrograph on the Hubble Space Telescope

Y. Homayouni, Gisella De Rosa, Rachel Plesha +62

We present reverberation mapping measurements for the prominent ultraviolet broad emission lines of the active galactic nucleus Mrk817 using 165 spectra obtained with the Cosmic Or…

A persistent ultraviolet outflow from an accreting neutron star binary transient

N. Castro Segura, C. Knigge, K. S. Long +31

All disc-accreting astrophysical objects produce powerful outflows. In binaries containing neutron stars (NS) or black holes, accretion often takes place during violent outbursts.…

UV and X-ray observations of the neutron star LMXB EXO 0748-676 in its quiescent state

A. S. Parikh, N. Degenaar, J. V. Hernandez Santisteban +5

The accretion behaviour in low-mass X-ray binaries (LMXBs) at low luminosities, especially at <E34 erg/s, is not well known. This is an important regime to study to obtain a comple…

Bow-shocks, nova shells, disc winds and tilted discs: The Nova-Like V341 Ara Has It All

N. Castro Segura, C. Knigge, J. A. Acosta-Pulido +21

V341 Ara was recently recognised as one of the closest (d ~ 150 pc) and brightest (V~ 10) nova-like cataclysmic variables. This unique system is surrounded by a bright emission neb…

The connection between the UV/optical and X-ray emission in the neutron star low-mass X-ray binary Aql X-1

E. López-Navas, N. Degenaar, A. S. Parikh +2

Accreting neutron stars and black holes in low-mass X-ray binaries (LMXBs) radiate across the electromagnetic spectrum. Linking the emission produced at different wavelengths can p…

Chandra reveals a possible ultra-fast outflow in the super-Eddington Be/X-ray binary Swift J0243.6+6124

J. van den Eijnden, N. Degenaar, N. S. Schulz +8

Accretion at super-Eddington rates is expected to be accompanied by strong outflows. Such outflows are observed in Galactic X-ray binaries and extragalactic Ultra-luminous X-ray so…

The black hole X-ray transient Swift J1357.2-0933 as seen with Swift and NuSTAR during its 2017 outburst

Aru Beri, B. E. Tetarenko, A. Bahramian +8

We report on observations of black hole Swift J1357.2-0933, a member of the modest population of very faint X-ray transients. This source has previously shown intense dips in the o…

An irradiated brown-dwarf companion to an accreting white dwarf

Juan V. Hernández Santisteban, Christian Knigge, Stuart P. Littlefair +7

Brown dwarfs and giant planets orbiting close to a host star are subjected to significant irradiation that can modify the properties of their atmospheres. In order to test the atmo…
