Detection of quasi-periodic micro-structure in three millisecond pulsars with the Large European Array for Pulsars
K. Liu, J. Antoniadis, C. G. Bassa +24
We report on the detection of quasi-periodic micro-structure in three millisecond pulsars (MSPs), PSRs J1022+1001, J2145-0750 and J1744-1134, using high time resolution data acquir…
The origin and evolution of the normal Type Ia SN 2018aoz with infant-phase reddening and excess emission
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +40
SN~2018aoz is a Type Ia SN with a -band plateau and excess emission in the infant-phase light curves 1 day after first light, evidencing an over-density of surface ir…
Robust parameter estimation from pulsar timing data
A. Samajdar, G. Shaifullah, A. Sesana +8
Recently, global pulsar timing arrays have released results from searching for a nano-Hertz gravitational wave background signal. Although there has not been any definite evidence…
Stripped-envelope stars in different metallicity environments. II. Type I supernovae and compact remnants
David R. Aguilera-Dena, Bernhard Müller, John Antoniadis +4
Stripped-envelope stars can be observed as Wolf-Rayet (WR) stars, or as less luminous hydrogen-poor stars with low mass loss rates and transparent winds. Both types are potential p…
Modelling annual scintillation arc variations in PSR J1643-1224 using the Large European Array for Pulsars
G. Mall, R. A. Main, J. Antoniadis +25
In this work we study variations in the parabolic scintillation arcs of the binary millisecond pulsar PSR J1643-1224 over five years using the Large European Array for Pulsars (LEA…
The International Pulsar Timing Array second data release: Search for an isotropic Gravitational Wave Background
J. Antoniadis, Z. Arzoumanian, S. Babak +123
We searched for an isotropic stochastic gravitational wave background in the second data release of the International Pulsar Timing Array, a global collaboration synthesizing decad…
Thermonuclear and Electron-Capture Supernovae from Stripped-Envelope Stars
Savvas Chanlaridis, John Antoniadis, David R. Aguilera-Dena +3
(abridged) When stripped from their hydrogen-rich envelopes, stars with initial masses between 7 and 11 M develop massive degenerate cores and collapse. Depending on…
