A Deconvolution Technique to Correct Deep Images of Galaxies from Instrumental Scattered Light
Emin Karabal, Pierre-Alain Duc, Harald Kuntschner +3
Deep imaging of the diffuse light emitted by the stellar fine structures and outer halos around galaxies is now often used to probe their past mass assembly. Because the extended h…
Spatially resolved star formation relation in two HI-rich galaxies with central post-starburst signature
Anne Klitsch, Martin A. Zwaan, Harald Kuntschner +3
E+A galaxies are post-starburst systems that are identified from their optical spectra. These galaxies contain a substantial young A-type stellar component, but have only little on…
KMOS view of the Galactic Centre - II. Metallicity distribution of late-type stars
A. Feldmeier-Krause, W. Kerzendorf, N. Neumayer +5
Knowing the metallicity distribution of stars in the Galactic Centre has important implications for the formation history of the Milky Way nuclear star cluster. However, this distr…
New Constraints on a complex relation between globular cluster colors and environment
Mathieu Powalka, Thomas H. Puzia, Ariane Lançon +25
We present an analysis of high-quality photometry for globular clusters (GCs) in the Virgo cluster core region, based on data from the Next Generation Virgo Cluster Survey (NGVS) p…
Making SPIFFI SPIFFIER: Upgrade of the SPIFFI instrument for use in ERIS and performance analysis from re-commissioning
E. M. George, D. Gräff, H. Feuchtgruber +15
SPIFFI is an AO-fed integral field spectrograph operating as part of SINFONI on the VLT, which will be upgraded and reused as SPIFFIER in the new VLT instrument ERIS. In January 20…
The Atlas3D project -- XXXI. Nuclear radio emission in nearby early-type galaxies
Kristina Nyland, Lisa M. Young, Joan M. Wrobel +22
We present the results of a high-resolution, 5 GHz, Karl G. Jansky Very Large Array study of the nuclear radio emission in a representative subset of the Atlas3D survey of early-ty…
