Stellar tidal streams images
Listed in IVOA Registry (Virtual Observatory)
Tidal interactions between massive galaxies and their satellites are fundamental processes in a Universe with LAMBDA-Cold Dark Matter (LAMBDACDM) cosmology, redistributing material into faint features that preserve records of past galactic interactions.
Description
While stellar streams in the Local Group impressively demonstrate satellite disruption, they do not constitute a statistically significant sample. Constructing a substantial catalog of stellar streams beyond the Local Group remains challenging due to the difficulties in obtaining sufficiently deep, wide-field images of galaxies.
Despite their potential to illuminate dark matter distribution and galaxy formation processes overall, stellar streams remain underutilized as cosmological probes. Aims. The Stellar Tidal Stream Survey (STSS) addresses this observational gap by leveraging amateur telescopes to obtain deep, scientific-grade images of galactic outskirts, capable of building a more statistically meaningful sample of stellar streams.

Over the last decade, the STSS has acquired deep (up to surface brightness limit ~28.3mag/arcsec^2^ in the r-band) wide-field images of 15 nearby Milky Way analog galaxies using a coordinated network of robotic amateur telescopes, avoiding the issues associated with "mosaicing" smaller images taken with a single, professional telescope. Our survey has revealed a diverse range of previously unreported faint features related to dwarf satellite accretion -- including stellar streams, shells, The STSS demonstrates the suitability of modern amateur telescopes to detect and study faint, diffuse structures in large fields around nearby spiral galaxies.
Their economic and accessibility advantages enable larger statistical samples with deep imaging, essential for testing galaxy formation models and constraining the frequency and properties of minor merger events in the local Universe.
