Radio Follow-Up Observations of a Weak-Line Quasar Exhibiting Remarkable X-ray Variability
Ayushi Chhipa, M. Vivek, Nayana A. J. +6
SDSSJ1539+3954 (), a radio-quiet weak-line quasar (WLQ), exhibited exceptional X-ray variability in 20192020, with its X-ray flux increasing by over 20 times fro…

Modelling the energy dependent X-ray variability of Mrk 335
K. Akhila, Ranjeev Misra, Rathin Sarma +2
We present a technique which predicts the energy dependent fractional r.m.s for linear correlated variations of a pair of spectral parameters and apply it to an XMM-Newton observat…

Serendipitous detection of an intense X-ray flare in the weak-line T Tauri star KM Ori with SRG/eROSITA
Savithri H. Ezhikode, Hema Anilkumar, R. Arun +8
Weak-line T Tauri stars (WTTS) exhibit X-ray flares, likely resulting from magnetic reconnection that heats the stellar plasma to very high temperatures. These flares are difficult…
