Kinematically cold and warm planetary nebulae samples, HII regions and supernovae remnants in the disc of the face-on spiral galaxy NGC 628 (M74) -- The Planetary Nebulae Spectrograph with the H arm

Magda Arnaboldi, Ortwin Gerhard, Surya Aniyan +14

We present the results for the galaxy NGC 628 observed with the Planetary Nebulae Spectrograph (PN.S) equipped with the H arm. With the third PN.S arm, the H arm, we measure…

Double progenitor origin of the S-star cluster

Sill Verberne, Elena Maria Rossi, Sergey E. Koposov +3

The origin of the cluster of S-stars located in the Galactic Centre is tied to the supermassive black hole Sagittarius A*, but exactly how is still debated. In this paper, we inves…

Improved constraints on Galactic Centre ejection of hypervelocity stars based on novel search method

Sill Verberne, Elena Maria Rossi, Sergey E. Koposov +6

Hypervelocity stars (HVSs) are stars which have been ejected from the Galactic Centre (GC) at velocities of up to a few thousand km/s. They are tracers of the Galactic potential an…

Radial velocities from Gaia BP/RP spectra

Sill Verberne, Sergey E. Koposov, Elena M. Rossi +3

The Gaia mission has provided us full astrometric solutions for over 1.5B sources. However, only the brightest 34M of those have radial velocity measurements. As a proof of concept…

Planetary Nebula Velocities in the Disk and Bulge of M31

C. Halliday, D. Carter, T. J. Bridges +10

We present radial velocities for a sample of 723 planetary nebulae (PNe) in the disk and bulge of M31, measured using the WYFFOS fibre spectrograph on the William Herschel telescop…
