CDM Tensions: Localising Missing Physics through Consistency Checks

Ö Akarsu, EÓ Colgáin, AA Sen… - arxiv preprint arxiv …, 2024 - arxiv.org
$\Lambda $ CDM tensions are by definition model dependent; one sees anomalies through
the prism of $\Lambda $ CDM. Thus, progress towards tension resolution necessitates …

[PDF][PDF] A panchromatic journey in the quasar environment: wandering through the same place at different times

B Trefoloni - 2025 - tesidottorato.depositolegale.it
Active Galactic Nuclei (AGN) are incredibly bright and powerful objects. Because of their
luminosity and prevalence, I observe them across all cosmic times, and their effects on their …
