MAGIS (Measuring Abundances of red super Giants with Infrared Spectroscopy) project I. Establishment of an abundance analysis procedure for red supergiants and its evaluation with nearby stars

Daisuke Taniguchi, Noriyuki Matsunaga, Naoto Kobayashi +11

[Abbreviated] Context. Given their high luminosities (L>~10^4Lsun), red supergiants (RSGs) are good tracers of the chemical abundances of the young stellar population in the Milky…

MICONIC: Dual active galactic nuclei, star formation, and ionised gas outflows in NGC 6240 seen with MIRI/JWST

L. Hermosa Muñoz, A. Alonso-Herrero, A. Labiano +19

As part of the guaranteed time observations program Mid-Infrared Characterization Of Nearby Iconic galaxy Centers (MICONIC), we used the medium-resolution spectrometer (MRS) of the…

Extragalactic globular cluster near-infrared spectroscopy: I. Integrated near-infrared spectra of Centaurus A/NGC 5128

L. G. Dahmer-Hahn, A. L. Chies-Santos, E. Eftekhari +6

One way to constrain the evolutionary histories of galaxies is to analyse their stellar populations. In the local Universe, our understanding of the stellar population properties o…

The formation and stability of a cold disc made out of stellar winds in the Galactic Centre

Diego Calderón, Jorge Cuadra, Christopher M. P. Russell +3

The reported discovery of a cold (~10 K) disc-like structure within 0.005 pc around the super-massive black hole at the centre of the Milky Way, Sgr A*, has challenged our unde…

The Lyman Alpha Reference Sample. XVI. Global 21cm HI properties of Lyman- emitting galaxies

A. Le Reste, M. J. Hayes, J. M. Cannon +9

The Lyman- (Lya) line of hydrogen is a well-known tracer of galaxies at high-z. However, the connection between Lya observables and galaxy properties has not fully been establis…
