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…
