NGTS-21b: An Inflated Super-Jupiter Orbiting a Metal-poor K dwarf
Douglas R. Alves, James S. Jenkins, Jose I. Vines +29
We report the discovery of NGTS-21b, a massive hot Jupiter orbiting a low-mass star as part of the Next Generation Transit Survey (NGTS). The planet has a mass and radius of $2.36…
A Decade of Black-Hole X-ray Binary Transients
Philip A Charles, David A H Buckley, Enrico Kotze +7
The last decade has seen a significant gain in both space and ground-based monitoring capabilities, producing vastly better coverage of BH X-ray binaries during their (rare) transi…
Synchronous X-ray/Optical QPOs from the Black Hole LMXB MAXI J1820+070
Jessymol K. Thomas, David A. H. Buckley, Philip A. Charles +10
We present high-speed optical photometry from SAAO and SALT on the black hole LMXB \MAXI (ASSASN-18ey), some of it simultaneous with NICER, Swift and Insight-HXMT X-ray coverage. W…
Large optical modulations during 2018 outburst of MAXI J1820+070 reveal evolution of warped accretion disc through X-ray state change
Jessymol K. Thomas, Philip A. Charles, David A. H. Buckley +5
The black-hole X-ray transient MAXI J1820+07 (=ASSASN-18ey) discovered in March 2018 was one of the optically brightest ever seen, which has resulted in very detailed optical outbu…
NGTS-19b : A high mass transiting brown dwarf in a 17-day eccentric orbit
Jack S. Acton, Michael R. Goad, Matthew R. Burleigh +34
We present the discovery of NGTS-19b, a high mass transiting brown dwarf discovered by the Next Generation Transit Survey (NGTS). We investigate the system using follow up photomet…
NGTS 15b, 16b, 17b and 18b: four hot Jupiters from the Next Generation Transit Survey
Rosanna H. Tilbrook, Matthew R. Burleigh, Jean C. Costes +36
We report the discovery of four new hot Jupiters with the Next Generation Transit Survey (NGTS). NGTS-15b, NGTS-16b, NGTS-17b, and NGTS-18b are short-period (d) planets orbiti…
Ultra-High Energy Neutrino Afterglows of nearby Long Duration Gamma-Ray Bursts
Jessymol K. Thomas, Reetanjali Moharana, Soebur Razzaque
Detection of ultra-high energy (UHE, PeV) neutrinos from astrophysical sources will be a major advancement in identifying and understanding the sources of UHE cosmic ra…
