ELAIS-N1 deep field uGMRT Band-2: constraints on diffuse Galactic synchrotron emission power spectrum
Rashmi Sagar, Abhirup Datta, Arnab Chakraborty +13
We present high sensitivity, low radio frequency continuum observations of the ELAIS-N1 field with 32 hours of observations of the uGMRT Band-2 ( MHz) covering $5.86\,\tex…
Hydrodynamical simulations of proton ingestion flashes in Type I X-ray Bursts
Simon Guichandut, Michael Zingale, Andrew Cumming
We perform the first multidimensional fluid simulations of thermonuclear helium ignition underneath a hydrogen-rich shell. This situation is relevant to Type I X-ray bursts on neut…
The imprint of convection on Type I X-ray bursts: Pauses in photospheric radius expansion lightcurves
Simon Guichandut, Andrew Cumming
Motivated by the recent observation by NICER of a type I X-ray burst from SAX J1808.4-3658 with a distinct "pause" feature during its rise (Bult et al. 2019), we show that bursts w…
Fast neutrino cooling in the accreting neutron star MXB 1659-29
Melissa Mendes, Farrukh J. Fattoyev, Andrew Cumming +1
Modelling of crust heating and cooling across multiple accretion outbursts of the low mass X-ray binary MXB 1659-29 indicates that the neutrino luminosity of the neutron star core…
Expanded atmospheres and winds in Type I X-ray bursts from accreting neutron stars
Simon Guichandut, Andrew Cumming, Maurizio Falanga +2
We calculate steady-state models of radiation-driven super-Eddington winds and static expanded envelopes of neutron stars caused by high luminosities in type I X-ray bursts. We use…
Swift observations of two outbursts from the magnetar 4U 0142+61
R. F. Archibald, V. M. Kaspi, P. Scholz +3
4U 0142+61 is one of a small class of persistently bright magnetars. Here we report on a monitoring campaign of 4U 0142+61 from 2011 July 26 - 2016 June 12 using the Swift X-ray Te…
A Magnetar-like Outburst from a High-B Radio Pulsar
R. F. Archibald, V. M. Kaspi, S. P. Tendulkar +1
Radio pulsars are believed to have their emission powered by the loss of rotational kinetic energy. By contrast, magnetars show intense X-ray and gamma-ray radiation whose luminosi…
The link between coherent burst oscillations, burst spectral evolution and accretion state in 4U 1728-34
Guobao Zhang, Mariano Mendez, Michael Zamfir +1
Coherent oscillations and the evolution of the X-ray spectrum during thermonuclear X-ray bursts in accreting neutron-star X-ray binaries have been studied intensively but separatel…
