Visplot: A visibility plot and observation scheduling tool for astronomical observatories
Emanuel Gafton, Illa R. Losada
We present Visplot, a free, open-source, web-based tool for hardware-aware visibility analysis and heuristic scheduling of both sidereal and non-sidereal astronomical observations.…
First detection of VHE gamma-ray signal from the FSRQ TON 0599
MAGIC Collaboration, K. Abe, S. Abe +245
TON\,0599 (z=0.7247) belongs to the few flat spectrum radio quasars (FSRQs) detected in the very high energy (VHE, \,GeV) gamma-ray band. Its redshift makes it currently o…
Alpha-element abundance patterns in star-forming regions of the local Universe
C. Esteban, J. E. Méndez-Delgado, J. GarcÃa-Rojas +6
(Abridged) We reassess the alpha-element abundance ratios (Ne/O, S/O, Ar/O) with respect to metallicity in ~1000 spectra of Galactic and extragalactic HII regions and star-forming…
The wide binary frequency of metal-poor stars
N. Lodieu, A. Pérez Garrido, J. -Y. Zhang +5
This study is aimed at identifying possible low-mass and sub-stellar companions to stars with well-determined metallicities. We investigate the multiplicity of metal-poor stars alo…
