Transition dynamics in the ${\Lambda }_{\mathrm{s}}$CDM model: Implications for bound cosmic structures

Evangelos A. Paraskevas, Arman Cam, Leandros Perivolaropoulos +1

We explore the predictions of ${\Lambda }_{\mathrm{s}}$CDM, a novel framework suggesting a rapid anti-de Sitter (AdS) to de Sitter (dS) vacua transition in the late Universe, on bound cosmic str…
