Ubiquitous signs of interactions in early-type galaxies with prolate rotation

no code implementations8 Mar 2021 Ivana Ebrová, Michal Bílek, Ana Vudragović, Mustafa K. Yıldız, Pierre-Alain Duc

We collected a sample of 19 nearby ETGs with distinct prolate rotation from the literature and inspected their ground-based deep optical images for interaction signs - 18 in archival images and one in a new image obtained with the Milankovi\'c telescope.

Learnable Gabor modulated complex-valued networks for orientation robustness

no code implementations23 Nov 2020 Felix Richards, Adeline Paiement, Xianghua Xie, Elisabeth Sola, Pierre-Alain Duc

Robustness to transformation is desirable in many computer vision tasks, given that input data often exhibits pose variance.

The MATLAS survey of faint outskirts of bright galaxies

no code implementations1 Nov 2020 Michal Bílek, Pierre-Alain Duc

In our contribution, we will present the various types of objects and features seen in our images, for example tidal features, faint star-forming regions in otherwise quenched galaxies, or faint dust clouds in our own Galaxy.
