EDGES-3: Instrument Design and Commissioning
Rigel C. Cappallo, Alan E. E. Rogers, Colin J. Lonsdale +10
EDGES-3 is the third iteration of the EDGES experiment, designed to measure the predicted global absorption feature in the radio spectrum produced by neutral hydrogen gas at cosmic…
A Bayesian approach to modelling spectrometer data chromaticity corrected using beam factors -- II. Model priors and posterior odds
Peter H. Sims, Judd D. Bowman, Steven G. Murray +8
The reliable detection of the global 21-cm signal, a key tracer of Cosmic Dawn and the Epoch of Reionization, requires meticulous data modelling and robust statistical frameworks f…
A general Bayesian model-validation framework based on null-test evidence ratios, with an example application to global 21-cm cosmology
Peter H. Sims, Steven G. Murray, Judd D. Bowman +8
Comparing composite models for multi-component observational data is a prevalent scientific challenge. When fitting composite models, there exists the potential for systematics fro…
Probing the Stellar Wind of the Wolf-Rayet Star in IC 10 X-1
Sayantan Bhattacharya, Silas G. T. Laycock, Andre-Nicolas Chene +5
IC 10 X-1 is an eclipsing high mass X-ray binary (HMXB) containing a stellar-mass black hole (BH) and a Wolf-Rayet (WR) donor star with an orbital period of P = 34.9 hr. This binar…
Analytic approximations of scattering effects on beam chromaticity in 21-cm global experiments
Alan E. E. Rogers, John P. Barrett, Judd D. Bowman +6
Scattering from objects near an antenna produce correlated signals from strong compact radio sources in a manner similar to those used by the Sea Interferometer to measure the radi…
A Bayesian approach to modelling spectrometer data chromaticity corrected using beam factors -- I. Mathematical formalism
Peter H. Sims, Judd D. Bowman, Nivedita Mahesh +7
Accurately accounting for spectral structure in spectrometer data induced by instrumental chromaticity on scales relevant for detection of the 21-cm signal is among the most signif…
The Wolf-Rayet + Black Hole Binary NGC 300 X-1: What is the Mass of the Black Hole?
Breanna A. Binder, Janelle M. Sy, Michael Eracleous +6
We present new X-ray and UV observations of the Wolf-Rayet + black hole binary system NGC 300 X-1 with the Chandra X-ray Observatory and the Hubble Space Telescope Cosmic Origins S…
The Great Pretenders Among the ULX Class
D. M. Christodoulou, S. G. T. Laycock, D. Kazanas +2
The recent discoveries of pulsed X-ray emission from three ultraluminous X-ray (ULX) sources have finally enabled us to recognize a subclass within the ULX class: the great pretend…
The X-ray Binary Population of the Nearby Dwarf Starburst Galaxy IC 10: Variable and Transient X-ray Sources
Silas G. T. Laycock, Rigel Cappallo, Benjamin F. Williams +3
We have monitored the Cassiopeia dwarf galaxy (IC 10) in a series of 10 Chandra ACIS-S observations to capture its variable and transient X-ray source population, which is expected…
Chandra and XMM Monitoring of the Black Hole X-ray Binary IC 10 X-1
Silas G. T. Laycock, Rigel C. Cappallo, Matthew J. Moro
The massive black hole + Wolf-Rayet binary IC10 X-1 was observed in a series of 10 Chandra and 2 XMM-Newton observations spanning 2003-2012, showing consistent variability around 7…
A Transient Supergiant X-ray Binary in IC10. An Extragalactic SFXT?
Silas Laycock, Rigel Cappallo, Kathleen Oram +1
We report the discovery of a large amplitude (factor of 100) X-ray transient (IC 10 X-2, CXOU J002020.99+591758.6) in the nearby dwarf starburst galaxy IC10 during our Chandr…
