SPECULATE: A synthetic spectral library, emulator and fitting package for accretion disc winds -- Infrastructure and application to CVs

Austen G. W. Wallis, Christian Knigge, James H. Matthews +6

Disc winds are critical components of accreting astrophysical systems and their observations can yield a wide variety of spectral line profiles. Yet, inferring disc wind parameters…

COPAS: Compact Objects and the Physics of Accretion Survey I. Accreting Binaries with P < 83 Minutes

Wendy Mendoza, Liliana Rivera Sandoval, Jan Kára +9

We present the first results from the Compact Objects and the Physics of Accretion Survey (COPAS), a high-cadence photometric survey focused on the detection of accreting white dwa…

Shedding far-ultraviolet light on the donor star and evolutionary state of the neutron-star LMXB Swift J1858.6-0814

N. Castro Segura, C. Knigge, J. H. Matthews +13

The evolution of accreting X-ray binary systems is closely coupled to the properties of their donor stars. As a result, we can constrain the evolutionary track a system is by estab…

A disc wind model for blueshifts in quasar broad emission lines

James H. Matthews, Jago Strong-Wright, Christian Knigge +7

Blueshifts - or, more accurately, blue asymmetries - in broad emission lines such as CIV 1550 are common in luminous quasars and correlate with fundamental properties such as Ed…

Evidence for mass-dependent peculiar velocities in compact object binaries: Towards better constraints on natal kicks

Yue Zhao, Poshak Gandhi, Cordelia Dashwood Brown +4

We compile a catalogue of low-mass and high-mass X-ray binaries, some recently reported binaries that likely host a neutron star (NS) or a black hole (BH), and binary pulsars (a pu…

Cataclysmic variables are a key population of gravitational wave sources for LISA

S. Scaringi, K. Breivik, T. B. Littenberg +3

The gravitational wave (GW) signals from the Galactic population of cataclysmic variables (CVs) have yet to be carefully assessed. Here we estimate these signals and evaluate their…
