A study of optical observing techniques for extra-galactic supernova remnants: Case of NGC300 [PDF]
Serbian Astronomical Journal, 2012 We present the results of a study of observational and identification techniques used for surveys and spectroscopy of candidate supernova remnants (SNRs) in the Sculptor Group galaxy NGC300.

, 2022 In the last years, precision astrometry has shown incredible potential as a tool to investigate the formation and evolution of our Galaxy and the Local Group. The future for this kind of science appears even brighter, with several facilities that will be dedicated to its further development. In this talk I will focus on MICADO, which is the first-light

Gaia: The Astrometry Revolution [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractThe power of micro-arcsecond (μas) astrometry is about to be unleashed. ESA's Gaia mission, now headed towards the end of the first year of routine science operations, will soon fulfil its promise for revolutionary science in countless aspects of Galactic astronomy and astrophysics.

A Slowly Pulsating Run‐Away B Star at High Galactic Latitude Ejected From a Spiral Arm
Astronomische Nachrichten, EarlyView.ABSTRACT We report the discovery of the young B6 V run‐away star LAMOST J083323.18 + 430825.4, 2.5 kpc above the Galactic plane. Its atmospheric parameters and chemical composition are determined from LAMOST spectra, indicating normal composition. Effective temperature (Teff$$ {T}_{\mathrm{eff}} $$ = 14,500$$ \mathrm{14,500} $$ K) and gravity (logg ...

Gaia Search for Stellar Companions of TESS Objects of Interest V
Astronomische Nachrichten, EarlyView.ABSTRACT In this paper, we present the latest results of our ongoing multiplicity survey of (Community) TESS Objects of Interest, using astrometry and photometry from the latest data release of the ESA Gaia mission to detect stellar companions of these stars and to characterize their properties.

On the Age Distribution of Classical Cepheids in the Galaxy
Astronomische Nachrichten, EarlyView.ABSTRACT We revisit the problem of the positive correlation between age and Galactocentric distance seen in Galactic Classical Cepheids, which at first sight may seem counter‐intuitive in the context of inside‐out galaxy formation. To explain it, we use the Besançon Galaxy Model and a simulation of star particles in the Galactic disc coupled with ...
