Radio-loudness statistics of quasars from Quaia-VLASS

Nestor Arsenov, Sandor Frey, András Kovács +1

Quasars are objects of high interest in extragalactic astrophysics, cosmology, and astrometry. One of their useful qualities is their potential radio loudness. However, the fractio…

Chemical inventory of the envelope of the Class I protostar L1551 IRS 5

P. Marchand, A. Coutens, J. Scigliuto +5

Episodic accretion in protostars leads to luminosity outbursts that end up heating their surroundings. This rise in temperature pushes the snow lines back, enabling the desorption…

The GALAH survey: Tracing the Milky Way's formation and evolution through RR Lyrae stars

Valentina D'Orazi, Nicholas Storm, Andrew R. Casey +39

Stellar mergers and accretion events have been crucial in shaping the evolution of the Milky Way (MW). These events have been dynamically identified and chemically characterised us…

Orbital dynamics in galactic potentials under mass transfer

Eduárd Illés, Dániel Jánosi, Tamás Kovács

Time-dependent potentials are common in galactic systems that undergo significant evolution, interactions, or encounters with other galaxies, or when there are dynamic processes li…

Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry

Gaia Collaboration, P. Panuzzo, T. Mazeh +412

Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…

On the Scarcity of Dense Cores ( cm) in High Latitude Planck Galactic Cold Clumps

Fengwei Xu, Ke Wang, Tie Liu +34

High-latitude () molecular clouds have virial parameters that exceed 1, but whether these clouds can form stars has not been studied systematically. Using JCMT SCUB…

Revisiting a Core-Jet Laboratory at High Redshift: Analysis of the Radio Jet in the Quasar PKS 2215+020 at z=3.572

Sándor Frey, Judit Fogasy, Krisztina Perger +4

The prominent radio quasar PKS 2215+020 (J2217+0220) was once labelled as a new laboratory for core--jet physics at redshift z=3.572 because of its exceptionally extended jet struc…
