Revealing HI gas in emission and absorption on pc to kpc scales in a galaxy at z ~ 0.017

N. Gupta, R. Srianand, J. S. Farnes +6

We present a detailed study of the quasar-galaxy pair: J1243+4043 - UGC07904. The sight line of the background quasar ( = 1.5266) passes through a region of the galaxy (=…

SiO Maser Survey towards off-plane O-rich AGBs around the orbital plane of the Sagittarius Stellar Stream

Yuanwei Wu, Noriyuki Matsunaga, Ross A. Burns +1

We conducted an SiO maser survey towards 221 O-rich AGB stars with the aim of identifying maser emission associated with the Sagittarius stellar stream. In this survey, maser emiss…

The radio structure of the peculiar narrow-line Seyfert 1 galaxy candidate J1100+4421

K. É. Gabányi, S. Frey, Z. Paragi +5

Narrow-line Seyfert 1 galaxies (NLS1) are an intriguing subclass of active galactic nuclei. Their observed properties indicate low central black hole mass and high accretion rate.…

Astrometric Galactic maser measurements cross-matched with Gaia

L. H. Quiroga-Nuñez, H. J. van Langevelde, M. J. Reid +4

Using the VLBA, the BeSSeL survey has provided distances and proper motions of young massive stars, allowing an accurate measure of the Galactic spiral structure. By the same techn…

Simulated Galactic methanol maser distribution to constrain Milky Way parameters

L. H. Quiroga-Nuñez, H. J. van Langevelde, M. J. Reid +1

Using trigonometric parallaxes and proper motions of masers associated with massive young stars, the Bar and Spiral Structure Legacy (BeSSeL) survey has reported the most accurate…
