The Meaning of Quasi‐Simultaneous X‐Rays and Gamma‐Ray Observations of RS Oph in Outburst

open access: yesAstronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT Shocks in novae outbursts are ubiquitous, but in symbiotic novae, they are particularly powerful, probably because of the surrounding red giant wind. The recurrent nova RS Oph is the best example of this phenomenon. The presence of shocked plasma in outburst was inferred from optical spectra, and it was confirmed by X‐ray observations since ...

Cloud Detection and Prediction with All Sky Cameras

open access: yesEPJ Web of Conferences, 2017
Atmospheric monitoring is a field of special importance for astroparticle physics, especially for Imaging Atmospheric Cherenkov Telescopes (IACTs) as clouds will absorb and scatter the Cherenkov photons of air showers.

Can XMM‐Newton Be Used to Track Compositional Changes in the Solar Wind?

open access: yesJournal of Geophysical Research: Space Physics, Volume 129, Issue 12, December 2024.
Abstract Geocoronal Solar Wind Charge Exchange (SWCX) is the process by which heavy ions from the solar wind undergo charge exchange with neutral hydrogen atoms from the Earth's exosphere, releasing photons at discrete energies characteristic of the solar wind ions. This paper investigates the solar wind types driving geocoronal SWCX.

Movement‐based cognitive training does not significantly shorten the learning curve for acquiring arthroscopic basic skills

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, Volume 32, Issue 9, Page 2463-2473, September 2024.
Abstract Purpose Skilful arthroscopy requires an aboveaverage level of manual dexterity. It is evident that particular motor skills can be learned and trained before arthroscopic training. The aim of this prospective cohort study was to investigate the impact of movement‐related cognitive training on the learning curve during arthroscopic basic ...

3C 84: Observational Evidence for Precession and a Possible Relation to TeV Emission

open access: yesGalaxies, 2019
3C 84 (NGC 1275, Perseus A) is a bright radio source at the center of an ongoing merger, where HST observations show two colliding spiral galaxies. 3C 84 holds promise to improve our understanding about how of the activity of active galactic nuclei, the ...

The relation between evaluative stances and narratological elements in an audio description script for theatre

open access: yesTradTerm, 2020
The question of neutrality in audio description (AD) has been discussed by professionals and researchers. Following several studies started by Praxedes Filho and Magalhães (2013, 2015), this article analyzes if evaluative stances identified via the ...

Status of the second phase of the MAGIC telescope

open access: yes, 2007
The MAGIC 17m diameter Cherenkov telescope will be upgraded with a second telescope with advanced photon detectors and ultra fast readout within the year 2007. The sensitivity of MAGIC-II, the two telescope system, will be improved by a factor of 2.

The MAGIC Telescopes - Status and Recent Results

open access: yesIl Nuovo Cimento C, 2011
The MAGIC telescopes are two Imaging Atmospheric Cherenkov Telescopes located on the canary island of La Palma. They provide the lowest energy threshold among existing instruments of the kind, reaching down to 50 GeV in standard trigger mode. This allows us to close the energy gap between satellite-bourne and ground-based gamma-ray observations for ...
