Small telescopes being effective: MAGIC or not?

open access: yesRAS Techniques and Instruments, 2023
Abstract The paper describes the MAGIC multimode focal reducer (Monitoring of Active Galaxies by Investigation of their Cores), commissioned on the 1-m Zeiss-1000 telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences in 2020 September.

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.

Sub-GeV Gamma Rays from Nearby Seyfert Galaxies and Implications for Coronal Neutrino Emission

open access: yesThe Astrophysical Journal Letters
Recent observations of high-energy neutrinos by IceCube and gamma rays by the Fermi Large Area Telescope (LAT) and the MAGIC telescope have suggested that neutrinos are produced in gamma-ray opaque environments in the vicinity of supermassive black holes.

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.

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 ...

Status and results of the MAGIC telescope [PDF]

open access: yesJournal of Physics: Conference Series, 2008
The MAGIC telescope is an imaging air Cherenkov telescope for very high energy gamma-ray astronomy. The scientific outcome of MAGIC at the end of its second cycle of observations includes outstanding results in both galactic and extragalactic physics. Among them the observation of periodic gamma-ray emission from the galactic binary system LSI+61, an ...

Adapting STEMM in Hawaiʻi: Necessary actions for one of the most diverse places in the United States

open access: yesJournal of Cellular Physiology, Volume 239, Issue 7, July 2024.
Hawai'i's diverse population prime it to be an exemplary environment to study representation in science, technology, engineering, mathematics, and medicine (STEMM). This graphical abstract juxtaposes the idealized version of Hawai'i that negates its complex history in favor of evocative imagery, with lessons in STEMM highlighting areas of improvement ...

Not So Fast: A New Catalog of Meteor Persistent Trains

open access: yesJournal of Geophysical Research: Space Physics, Volume 129, Issue 7, July 2024.
Abstract This paper presents the results of a nearly 2‐year long campaign to detect and analyze meteor persistent trains (PTs)—self‐emitting phenomena which can linger up to an hour after their parent meteor. The modern understanding of PTs has been primarily developed from the Leonid storms at the turn of the century; our goal was to assess the ...
