Primordial Intermediate and Supermassive Black Hole formation during the electron-positron annihilation epoch
J. L. G. Sobrinho, P. Augusto
Some of the Intermediate Mass Black Hole (IMBH) candidates observed at the center of galaxies or in globular clusters and some of the Supermassive Black Holes (SMBHs) seen at the c…
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 : the…
Direct detection of Black Holes via electromagnetic radiation
J. L. G. Sobrinho, P. Augusto
Many black hole (BH) candidates exist, ranging from supermassive (-- M) to stellar masses (-- M), all of them identified by in…
