When will T Coronae Borealis next erupt as a nova? Constraints from recurrence, orbital phase, and accretion-state evolution
Songpeng Pei, Xiaowan Zhang, Renzhi Su +6
The paper combines historical eruption intervals, orbital phase information, and recent accretion‑state changes to give conditional probabilities and monitoring windows for the nex…
A FLASH HI absorption search in compact sources in the pilot ASKAP interplanetary scintillation field
Paris E. Gordon-Hall, Emily F. Kerrison, Elizabeth K. Mahony +13
The study uses ASKAP interplanetary scintillation measurements to identify compact radio sources and searches for redshifted HI 21 cm absorption between z = 0.4–1, detecting two ne…
Lack of Significant Orbital-Phase Locking in the Active Phases of the Recurrent Nova T CrB
Songpeng Pei, Xiaowan Zhang, Renzhi Su +6
T Coronae Borealis (T CrB) is a symbiotic recurrent nova (RN) that exhibits both nova eruptions and long-term active phases resembling superoutbursts and normal outbursts. Motivate…
One sightline, many systems: a FLASH discovery of HI towards scintillating quasar PKS 0405-385
E. F. Kerrison, H. Yoon, E. M. Sadler +15
We report the discovery of an intervening 21\,cm absorption line at z = 0.882 towards the z = 1.284 quasar PKS 0405-385, identified in the First Large Absorption Survey in HI (FLAS…
A jet-gas interaction beyond the host galaxy: detection of a neutral hydrogen outflow at cosmic noon
Renzhi Su, Stephen J. Curran, James R. Allison +6
We present upgraded Giant Metrewave Radio Telescope (uGMRT) observations of 0731+438, an \mbox{FR II} radio galaxy at a redshift of 2.429 with two lobes separated by 82 kpc. A blue…
Multi-wavelength study of the pre-eruption dip in the recurrent nova T Coronae Borealis preceding imminent nova eruption
Songpeng Pei, Xiaowan Zhang, Renzhi Su +6
We present a multi-wavelength study of the symbiotic recurrent nova (RN) T Coronae Borealis (T CrB) using Swift Burst Alert Telescope (BAT) / X-Ray Telescope (XRT) / UltraViolet Op…
