PublicationThe Nature of Fossil Galaxy Groups: Are They Really Fossils?
We use SDSS-DR4 photometric and spectroscopic data out to redshift z ~ 0.1 combined with ROSAT All Sky Survey X-ray data to produce a sample of 25 fossil groups...

PublicationThe nature of giant clumps in high-z discs: a deep-learning comparison of simulations and observations
We use deep learning to explore the nature of observed giant clumps in high-redshift disc galaxies, based on their identification and classification in...

PublicationThe Nature of Growing Bulges Within z < 1.3 Galaxy Disks in the GOODS-N Field
We analyze central surface brightness μ0, nuclear and global colors of intermediate redshift disk galaxies. On an apparent-diameter-limited sample of 398...

PublicationThe nature of HH 223 from long-slit spectroscopy
Context: HH 223 is a knotty, undulating nebular emission of ˜30 arcsec length found in the L723 star-forming region. It lies projected onto the largest...

PublicationThe nature of HHL 73 from optical imaging and integral field spectroscopy
We present new results on the nature of the Herbig-Haro-like object 73 (HHL 73, also known as [G84b] 11) based on narrow-band CCD Hα and [SII] images of the HHL...

PublicationThe nature of late-type spiral galaxies: structural parameters, optical and near-infrared colour profiles and dust extinction
We analyse V- and H-band surface photometry of a sample of 18 Sb-Sd galaxies. Combining high-resolution Hubble Space Telescope (HST) images with ground-based...

PublicationThe nature of LINER galaxies:. Ubiquitous hot old stars and rare accreting black holes
Context. Galaxies, which often contain ionised gas, sometimes also exhibit a so-called low-ionisation nuclear emission line region (LINER). For 30 years, this...

PublicationThe Nature of Luminous X-Ray Sources with Mid-Infrared Counterparts
We investigate the luminous X-ray sources in the Lockman Hole (LH) and the extended Groth strip (EGS) detected at 24 μm using the Multiband Imaging Photometer...
