Brightest Gamma-Ray-burst Flare Observed in GRB 221009A: Bridging the Last Gap between the Prompt Emission and Flare in Gamma-Ray Bursts

The Astrophysical Journal Letters
Flares are usually observed during the afterglow phases of Gamma-ray bursts (GRBs) in the soft-X-ray, optical, and radio bands—but rarely in the gamma-ray band.

Optical Flare Search on the RS CVn-type flare stars AR Lacertae

, 2022
We present the results of fast spectrophotometry of flares on the RS CVn-type star AR Lac with a time resolution of 34 s and a spectroscopic resolution R $\sim $ 1300. The observations were performed on July 21-22, 2021 with the 2.0 m Karl Zeiss telescope at the Terskol Observatory.

Statistical Study of the Timing of the Appearance of Hα Postflare Loops: Simple Scaling Law Based on Radiative Cooling

The Astrophysical Journal
Recent Sun-as-a-star studies have shown that postflare loops can manifest as a secondary peak in the H α light curve, suggesting that stellar postflare loops are detectable.

Systemic Corticosteroids in the Management of Sinonasal Disease: An Evidence‐Based Expert Review

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) is a prevalent, heterogeneous inflammatory disease associated with significant morbidity. Systemic corticosteroids (SCS) are commonly prescribed for their anti‐inflammatory effects, but cumulative exposure carries risks, including metabolic, cardiovascular, and skeletal complications.

RoboPol: optical polarization-plane rotations and flaring activity in blazars [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
We present measurements of rotations of the optical polarization of blazars during the second year of operation of RoboPol, a monitoring programme of an unbiased sample of gamma-ray bright blazars specially designed for effective detection of such events, and we analyse the large set of rotation events discovered in two years of observation.
