I will summarize the status of the Polish participation in the Vera Rubin Observatory and its overlap with other key observatories and instruments. I will highlight the scientific perspectives of the Rubin Observatory and its impact on Particle Astrophysics in Poland, illustrated by some recent scientific results from our team.
The expansion of the Universe at relatively small distances (up to redshifts about 9) can be measured with individual astrophysical sources. I will shortly list those types sources and the used techniques to determine the distance for each individual source. I will present the results of our group based on measurement of the time delays in quasars, and I will discuss the issue of the...
The Astrophysics Centre for Multimessenger studies in Europe is a new Horizon Europe-funded project for the years 2024-2028. It gathers 40 world-class collaborating institutions from 14 countries and brings together the astroparticle and astronomy communities for long-term collaboration.
ACME is a pathfinder to broaden and improve access to the research infrastructures services and data,...
Studies of galaxy clustering show that the relationship between luminous structures and the underlying dark matter distribution is not straightforward. It depends on various, often interrelated, elements, such as the properties of the galaxies or the properties of the environment which in these galaxies reside.
Crucial for these dark-luminous matter relations studies are estimates of the...
The effect of gravitational lensing of the cosmic microwave background
(CMB) provides a unique opportunity to obtain a picture of the
gravitational potential of the large-scale structure of the Universe
at very high redshifts. Tomographic cross-correlation of the
gravitational potential with other tracers of the large-scale
structure at known redshifts allows tracing the evolution of...
Low surface brightness galaxies (LSBs) are estimated to account for 30% to 60% of the total number density of galaxies. In this work, we analyze a dataset of LSBs identified by Thuruthipilly et al. in the Dark Energy Survey (DES) Data Release 1. The aim is to organize these galaxies into categories more detailed than the traditional blue and red classifications.
To achieve this, we apply...
