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.

Disease Remission: A Scoping Review With Thematic Analysis of the Scientific Literature With Implications for Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Remission, a term used to describe a goal of treatment for some chronic diseases, has recently been proposed for chronic rhinosinusitis (CRS). However, it is unclear what remission means for CRS and why it should serve as a goal in the present‐day treatment of CRS.

A Search for Minute-timescale Flares from the Transient AT 2024wpp

The Astrophysical Journal
The AT 2018cow-like fast blue optical transient AT 2022tsd showed a large number of a few-minute-duration, high-luminosity (∼10 ^43 erg s ^−1 ) flares. We present an intensive search for such flares from another 18cow-like event, AT 2024wpp. We have used

A multi-wavelength view of magnetic flaring from PMS stars [PDF]

, 2018
Flares from the Sun and other stars are most prominently observed in the soft X-ray band. Most of the radiated energy, however, is released at optical/UV wavelengths.

VLBI observations of flared optical quasar CGRaBS J0809+5341 [PDF]

Publications of the Astronomical Society of Japan, 2016
Abstract A bright optical flare was detected in the high-redshift (z = 2.133) quasar CGRaBS J0809+5341 on 2014 April 13. The absolute magnitude of the object reached −30.0 during the flare, making it the brightest one (in flaring stage) among all known quasars so far.

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

The Double Tidal Disruption Event AT 2022dbl Implies that at Least Some “Standard” Optical Tidal Disruption Events Are Partial Disruptions

The Astrophysical Journal Letters
Flares produced following the tidal disruption of stars by supermassive black holes can reveal the properties of the otherwise dormant majority of black holes and the physics of accretion.

Optical Polarimetric and Multiwavelength Flaring Activity of Blazar 3C 279 [PDF]

The Astrophysical Journal Supplement Series, 2019
Abstract An exhaustive analysis of 9 yr optical R-band photopolarimetric data of the flat-spectrum radio quasar 3C 279 from 2008 February 27 to 2017 May 25 is presented, along with multiwavelength observing campaigns performed during the flaring activity exhibited in 2009 February/March, 2011 June, 2014 March/April, 2015 June, and 2017 ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

New classification parameter of solar flares based on the maximum flux in soft X-rays and on duration of flare

, 2020
Solar flare activity is characterised by different classification systems, both in optical and X-ray ranges. The most generally accepted classifications of solar flares describe important parameters of flares such as the maximum of brightness of the ...
