Broadband multi-wavelength properties of M87 during the 2017 Event Horizon Telescope campaign

open access: yes, 2021
In 2017, the Event Horizon Telescope (EHT) Collaboration succeeded in capturing the first direct image of the center of the M87 galaxy. The asymmetric ring morphology and size are consistent with theoretical expectations for a weakly accreting ...

Turbulent parameters at different heights in the atmosphere. Shack–Hartmann wavefront sensor data

open access: yesSolar-Terrestrial Physics, 2022
The paper presents the results of studies of wavefront distortions at different heights in the atmosphere. We have used measurement wavefront data to determine optical turbulence parameters along the line of sight of the Large Solar Vacuum Telescope ...

The effect of proton damage on the X-ray spectral response of MOS CCDs for the swift X-ray telescope [PDF]

open access: yes, 2002
The effect of non-ionising energy loss(NIEL) of protons in charge-coupled devices is to displace silicon atoms and any dopant materials present from their lattice positions to form lattice defects which in turn can trap electrons [1].

Receiving vectors of muon telescope of cosmic ray station Novosibirsk

open access: yesSolar-Terrestrial Physics, 2016
The method of receiving vectors allows us to determine cosmic ray anisotropy at every moment of time. Also, the method makes it possible to study fast anisotropy fluctuations related to the interplanetary medium dynamics.

IMF dependence of the open-closed field line boundary in Saturn's ionosphere, and its relation to the UV auroral oval observed by the Hubble Space Telescope [PDF]

open access: yes, 2007
We study the dependence of Saturn's magnetospheric magnetic field structure on the interplanetary magnetic field (IMF), together with the corresponding variations of the open-closed field line boundary in the ionosphere.

Wishing for the Watch Face in Jonathan Swift’s “The Progress of Beauty”

open access: yesABO : Interactive Journal for Women in the Arts 1640-1830, 2018
This article illuminates the technological underpinnings of Jonathan Swift’s satire, “The Progress of Beauty” (1719), by exploring how eighteenth-century poetics of beauty and scientific progress pit human against automaton.
