Post-reionization HI 21-cm signal: A probe of negative cosmological constant

Chandrachud B. V. Dash, Tapomoy Guha Sarkar, Anjan A. Sen

In this study, we investigate a cosmological model involving a negative cosmological constant (AdS vacua in the dark energy sector). We consider a quintessence field on top of a ne…
