Cosmic Rulers: Masers as Tools for Probing Structure in the Galaxy and Beyond, from AU to kpc
Kazi L. J. Rygl, Anna Bartkiewicz, Olga Bayandina +9
Maser emission provides an unique window into astronomical sources across vast spatial scales - from tens to hundreds of astronomical units around protostars and evolved stars up t…
Jets and Outflows in Young Stellar Objects with the SKAO
Giovanni Sabatini, Gemma Busquet, Carlos Carrasco-González +48
Jets and outflows are ubiquitous phenomena associated with the formation of young stellar objects (YSOs). They play a crucial role in removing angular momentum from the accreting s…
A FAST search for radio pulsations during the dormant state of the AMSPs IGR J00291+5934 and MAXI J1957+032
A. Marino, E. Parent, F. Coti Zelati +15
Accreting millisecond pulsars (AMSPs) and transitional millisecond pulsars (tMSPs) are neutron star low-mass X-ray binaries which can evolve into "recycled" radio millisecond pulsa…
Detections of Compact Radio Continuum toward Methanol Maser Rings Using the VLA
Anna Bartkiewicz, Olga Bayandina, Alberto Sanna +5
High-mass protostars are deeply embedded in dust inside their natal cores and are not easily detectable. However, maser emission at centimeter wavelengths, owing to its high bright…
The Expanding 3 kpc Arms Are Neither Expanding nor Spiral Arms but X1 Orbits Driven by the Galactic Bar
Jayender Kumar, Mark J. Reid, T. M. Dame +6
Near the center of our Milky Way is a bar-like structure and the so-called Expanding 3-kpc arms. We currently have limited knowledge of this important region, since we are about 8.…
Protostellar Outflows at the EarliesT Stages (POETS). VII. Circumstellar gas kinematics traced by water masers inside the HC HII region NGC7538 IRS1
Luca Moscadelli, Ciriaco Goddi, Tomoya Hirota +1
This article focuses on NGC7538 IRS1, one of the most luminous and studied HC HII regions in the northern hemisphere. Our aim is to identify the young stellar objects (YSOs) embedd…
