24 sept. 2024 · The amazing web of Sciama's advisor ancestors, spanning a thousand years from the Islamic Golden Age to modernity, reveals how intricately human knowledge is woven through time and space,...
Il y a 4 jours · Drawing on ideas from neutrino astronomy, I will demonstrate how advancements in quantum sensor technology can provide new insights into light DM through multimessenger astronomy beyond the Standard Model, particularly if it manifests as macroscopic bosonic stars or emerges from transient astrophysical sources.
8 oct. 2024 · The Lambda-CDM, Lambda cold dark matter, or ΛCDM model is a mathematical model of the Big Bang theory with three major components: a cosmological constant, denoted by lambda (Λ), associated with dark energy. the postulated cold dark matter, denoted by CDM. ordinary matter.
4 oct. 2024 · An analytic model using a non-linear power spectrum (NLA) only matches the signal down to 20 h−1 Mpc. Our detection demonstrates that galaxy clustering in the non-linear regime of structure formation preserves an interpretable memory of the large-scale tidal field.
8 oct. 2024 · Aims. While the rapid assembly of halos can lead to increased halo masses upon the onset of collapse, it remains unclear if this leads to higher mass BH seeds. As a common route for halos to grow rapidly is via halo-halo mergers, we aim to test what effects such a merger occurring during the initial gas collapse has on the formation of BH seeds.
1 oct. 2024 · We present photometric redshifts (photo- z) for the deep wide fields of the Physics of the Accelerating Universe Survey (PAUS), covering an area of ∼ 50 deg 2 , for ∼ 1.8 million objects up to i A B <23 . The PAUS deep wide fields overlap with the W1 and W3 fields from CFHTLenS and the G09 field from KiDS/GAMA.
24 sept. 2024 · Here we present the DESI EDR white dwarf catalogue, which includes 2706 spectroscopically confirmed white dwarfs of which approximately 60 percnt have been spectroscopically observed for the first time, as well as 66 white dwarf binary systems.
