Effects of model incompleteness on the drift-scan calibration of radio telescopes

Bharat K. Gehlot, Daniel C. Jacobs, Judd D. Bowman +76

Precision calibration poses challenges to experiments probing the redshifted 21-cm signal of neutral hydrogen from the Cosmic Dawn and Epoch of Reionization (z~30-6). In both inter…

A new class of fossil fragments from the hierarchical assembly of the Galactic bulge

F. R. Ferraro, C. Pallanca, B. Lanzoni +12

The formation and evolutionary processes of galaxy bulges are still unclear, and the presence of young stars in the bulge of the Milky Way is largely debated. We recently demonstra…

Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) VI. Non-detection of sodium with HARPS on the bloated super-Neptune WASP-127b

J. V. Seidel, M. Lendl, V. Bourrier +17

WASP-127b is one of the puffiest exoplanets found to date, with a mass only Neptune masses, but a radius larger than Jupiter. It is also located at the border of the Neptune…

Dust and gas in the central region of NGC 1316 (Fornax A) -- Its origin and nature

T. Richtler, M. Hilker, E. Iodice

The early-type galaxy NGC 1316 hosts about 10^7 solar masses of dust within a central radius of 5 kpc. These prominent dust structures are believed to have an external origin, whic…

Dust and star formation in the centre of NGC 3311

T. Richtler, M. Hilker, M. Arnaboldi +1

NGC 3311 is the central galaxy of the Hydra I galaxy cluster. It has a hot interstellar medium and hosts a central dust lane with emission lines. These dust lanes are frequent in e…

The formation of compact dwarf ellipticals through merging star clusters

F. Urrutia Zapata, M. Fellhauer, A. G. Alarcon Jara +2

In the last decades, extended old stellar clusters have been observed. These extended objects cover a large range in masses, from extended clusters or faint fuzzies to ultra compac…
