Using Deep Learning Methods to Detect for Ultra-diffuse Galaxies in KiDS

Hao Su, Rui Li, Nicola R. Napolitano +13

Ultra-diffuse Galaxies (UDGs) are a subset of Low Surface Brightness Galaxies (LSBGs), showing mean effective surface brightness fainter than and a d…

Improved photometric redshift estimations through self-organising map-based data augmentation

Yun-Hao Zhang, Joe Zuntz, Irene Moskowitz +8

We introduce a framework for the enhanced estimation of photometric redshifts using Self-Organising Maps (SOMs). Our method projects galaxy Spectral Energy Distributions (SEDs) ont…

The fifth data release of the Kilo Degree Survey: Multi-epoch optical/NIR imaging covering wide and legacy-calibration fields

Angus H. Wright, Konrad Kuijken, Hendrik Hildebrandt +51

We present the final data release of the Kilo-Degree Survey (KiDS-DR5), a public European Southern Observatory (ESO) wide-field imaging survey optimised for weak gravitational lens…

Enhancing Photometric Redshift Catalogs Through Color-Space Analysis: Application to KiDS-Bright Galaxies

Priyanka Jalan, Maciej Bilicki, Wojciech A. Hellwing +11

We present a method to refine photometric redshift galaxy catalogs by comparing their color-space matching with overlapping spectroscopic calibration data. We focus on cases where…

New Kids in Town. Sextans~II: a new stellar system in the outskirts of the Milky Way

Massimiliano Gatto, Michele Bellazzini, Crescenzo Tortora +9

We report on the discovery of a significant and compact over-density of old and metal-poor stars in the KiDS survey (data release 4). The discovery is confirmed by deeper HSC-SSC d…

The dark matter halo masses of elliptical galaxies as a function of observationally robust quantities

Alessandro Sonnenfeld, Crescenzo Tortora, Henk Hoekstra +9

Context. The assembly history of the stellar component of a massive elliptical galaxy is closely related to that of its dark matter halo. Measuring how the properties of galaxies c…
