GammaLearn - first steps to apply Deep Learning to the Cherenkov Telescope Array data [PDF]

EPJ Web of Conferences, 2019
The Cherenkov Telescope Array (CTA) is the next generation of ground-based gamma-ray telescopes for gamma-ray astronomy. Two arrays will be deployed composed of 19 telescopes in the Northern hemisphere and 99 telescopes in the Southern hemisphere. Due to

Characterization and modelling of exoplanetary atmospheres

Comptes Rendus. Physique, 2023
The spectral characterization of exoplanetary atmospheres is a relatively new subject. Until recently, space and ground-based observatories allowed only a few planets to be observed with spectroscopic instruments.

Hydration Features on Near-Earth Objects: Integrating New Data with Prior Results

The Planetary Science Journal
Near-Earth objects (NEOs) are excellent laboratories for testing processes that affect airless bodies, as well as informing us about solar system history. Though most NEOs are nominally anhydrous because they formed inside the solar system frost line and

Review: the landscape of gravitational wave astronomy

Acta Polytechnica
The direct detection of gravitational waves from a binary black hole merger has opened a new window in observational astronomy. The first three observing runs of the LIGO/Virgo groundbased interferometers have produced a broad range of scientific ...

The Van Hoof Effect over the Blazhko Cycle

The Astrophysical Journal, 2023
We provide the first detection of the Van Hoof effect over a complete Blazhko cycle in the variations of H β , neutral, and ionized metallic lines, measurable on 2782 high-resolution line profiles obtained during the course of a 41 day continuous and ...

Development of a Monitoring System for an Infrared Camera [PDF]

Journal of Astronomy and Space Sciences, 2006
The KASINICS (KASI Near-Infrared Camera System) is a ground-based instrument developed by the Korea Astronomy and Space Science Institute (KASI). We developed a temperature and vacuum monitoring system for operating the KASINICS.

Parametric analysis of cherenkov light LDF from EAS for high energy gamma rays and nuclei: Ways of practical application

EPJ Web of Conferences, 2017
In this paper we propose a ‘knee-like’ approximation of the lateral distribution of the Cherenkov light from extensive air showers in the energy range 30–3000 TeV and study a possibility of its practical application in high energy ground-based gamma-ray ...

Cross-survey Image Transformation: Enhancing SDSS and DECaLS Images to Near-HSC Quality for Advanced Astronomical Analysis

The Astrophysical Journal Supplement Series
This study focuses on transforming galaxy images between astronomical surveys, specifically enhancing images from the Sloan Digital Sky Survey (SDSS) and the Dark Energy Camera Legacy Survey (DECaLS) to achieve quality comparable to the Hyper Suprime-Cam

Identifying Dust-lane Spheroidal Galaxies in DESI Legacy Imaging Surveys Using Semisupervised Methods

The Astrophysical Journal Supplement Series
Dust-lane spheroidal galaxies (DLSGs) are unique astrophysical systems that exhibit the morphology of early-type galaxies (ETGs) but are distinguished by prominent dust lanes.
