The cool-core galaxy cluster RXJ1720.1+2638 hosts extended radio emission near the cluster core, known as a minihalo. The origin of this emission is still debated and one piece of the puzzle has been the question of whether the supermassive black hol...

Signatures of non-thermal dark matter with kination and early matter domination. Gravitational waves versus laboratory searches (2022)
Journal Article
Ghoshal, A., Heurtier, L., & Paul, A. (2022). Signatures of non-thermal dark matter with kination and early matter domination. Gravitational waves versus laboratory searches. Journal of High Energy Physics, 2022(12), Article 105. https://doi.org/10.1007/jhep12%282022%29105

The non-thermal production of dark matter (DM) usually requires very tiny couplings of the dark sector with the visible sector and therefore is notoriously challenging to hunt in laboratory experiments. Here we propose a novel pathway to test such a... Read More about Signatures of non-thermal dark matter with kination and early matter domination. Gravitational waves versus laboratory searches.

The Milky Way’s plane of satellites is consistent with ΛCDM (2022)
Journal Article

The Milky Way is surrounded by 11 ‘classical’ satellite galaxies in a remarkable configuration: a thin plane that is possibly rotationally supported. Such a structure is thought to be highly unlikely to arise in the standard (ΛCDM) cosmological model... Read More about The Milky Way’s plane of satellites is consistent with ΛCDM.
