The long freeze: an asymptotically static universe from holographic dark energy

Samuel Blitz, Robert J. Scherrer, Oem Trivedi

We show that some holographic dark energy models can lead to a future evolution of the universe in which the scale factor is asymptotically constant, while $\dot a \rightarrow…

New perspectives on future rip scenarios with holographic dark energy

Oem Trivedi, Robert J. Scherrer

We explore the asymptotic future evolution of holographic dark energy (HDE) models, in which the density of the dark energy is a function of a cutoff scale . We develop a genera…

ULDM self-interactions, tidal effects and tunnelling out of satellite galaxies

Bihag Dave, Gaurav Goswami

It is well-known that Dark Matter (DM) inside a satellite galaxy orbiting a host halo experiences a tidal potential. If DM is ultra-light, given its wave-like nature, one expects i…

Self-interactions of ULDM to the rescue?

Bihag Dave, Gaurav Goswami

One of the most important questions in cosmology is concerning the fundamental nature of dark matter (DM). DM could consist of spinless particles of very small mass i.e. $m \sim 10…

Trans-Planckian Censorship Conjecture and Non-thermal post-inflationary history

Mansi Dhuria, Gaurav Goswami

The recently proposed Trans-Planckian Censorship Conjecture (TCC) can be used to constrain the energy scale of inflation. The conclusions however depend on the assumptions about po…
