Stellar mass Primordial Black Holes as Cold Dark Matter

J. L. G. Sobrinho, P. Augusto

Primordial Black Holes (PBHs) might have formed in the early Universe due to the collapse of density fluctuations. PBHs may act as the sources for some of the gravitational waves r…

New thresholds for Primordial Black Hole formation during the QCD phase transition

J. L. G. Sobrinho, P. Augusto, A. L. Gonçalves

Primordial Black Holes (PBHs) might have formed in the early Universe as a consequence of the collapse of density fluctuations with an amplitude above a critical value $δ_{c}$ : the…

Direct detection of Black Holes via electromagnetic radiation

J. L. G. Sobrinho, P. Augusto

Many black hole (BH) candidates exist, ranging from supermassive ( $\sim 1 0^{6}$ -- $1 0^{10}$ M $_{⊙}$ ) to stellar masses ( $\sim 1$ -- $100$ M $_{⊙}$ ), all of them identified by in…
