A heterogeneous set of unusual quasars selected from astrometry and broad-band photometry
C. Cheng, K. Valeckas, L. Christensen +7
The aim of this study is to explore methods for how to identify new quasars with different properties with regard to reddening, redshift, the presence of broad absorption lines fro…
Radial abundance gradients of 18 elements in Galactic open clusters from infrared MWM spectra A detailed analysis of 655 giants in 133 clusters
S. Bijavara Seshashayana, H. Jönsson, V. D'Orazi +3
Open clusters are powerful tools for studying the Milky Way. While large spectroscopic surveys now provide spectra for many cluster members, automated pipelines and heterogeneous m…
Stellar Population Astrophysics (SPA) with the TNG. Beyond the iron peak: Galactic evolution of molybdenum, ruthenium and zirconium through open clusters
Natalia Alvarez-Baena, Valentina D'Orazi, Christopher Sneden +11
Context: Open clusters serve as key laboratories for studying the chemical evolution of the Milky Way. In particular, leveraging these coeval groups of stars to study elements beyo…
SN 2025aico: Early observations of a faint Type IIb supernova with a low-mass envelope
J. -W. Zhao, A. Pastorello, B. Kumar +45
We aimed to investigate the physical properties and the underlying explosion mechanisms of the Type IIb SN 2025aico. Through a comprehensive analysis of early-phase optical light c…
A Near-Infrared and Optical Study of NGC 5822: An Open Cluster Hosting Barium-stars and Lithium-Enriched Giant Stars
N. Holanda, V. Loaiza-Tacuri, A. Sonally +7
We present a chemical abundance study of giant stars in the Galactic open cluster NGC 5822, which hosts two barium stars (#002 and #201) and three lithium-enriched giants (#006, #1…
Stellar Population Astrophysics (SPA) with the TNG 23 IR elemental abundances of 114 giant stars in 41 Open Clusters
Shilpa Bijavara Seshashayana, Henrik Jönsson, Valentina D'Orazi +4
Open clusters have been extensively used as tracers of Galactic chemical evolution, as their constituent stars possess shared characteristics, including age, Galactocentric radius,…
Stellar population astrophysics (SPA) with the TNG. The Phosphorus abundance on the young side of MilkyWay
Mingjie Jian, Xiaoting Fu, Valentina D'Orazi +11
We present phosphorus abundance measurements for a total of 102 giant stars, including 82 stars in 24 open clusters and 20 Cepheids, based on high-resolution near-infrared spectra…
Discovery and Analysis of Afterglows from Poorly Localised GRBs with the Gravitational-wave Optical Transient Observer (GOTO) All-sky Survey
Amit Kumar, B. P. Gompertz, B. Schneider +86
Gamma-ray bursts (GRBs), particularly those detected by wide-field instruments such as the Fermi/GBM, pose a challenge for optical follow-up due to their large initial localisation…
Exploring fluorine chemical evolution in the Galactic disk: the open cluster perspective
Shilpa Bijavara Seshashayana, Henrik Jönsson, Valentina D'Orazi +6
Open clusters are ideal tools for tracing the abundances of different elements because their stars are expected to have the same age, distance, and metallicity. Therefore, they ser…
