Space-time waves from a collapse with a time dependent cosmological parameter
Jaime Mendoza Hernández, Mauricio Bellini, Claudia Moreno
We study the emission of space-time waves produced by back-reaction effects during a collapse of a spherically symmetric universe with a time dependent cosmological parameter, whic…

Waves of space-time from a collapsing compact object
Jaime Mendoza Hernández, Juan Ignacio Musmarra, Mauricio Bellini
We study the partial time dependent collapse of a spherically symmetric compact object with initial mass and final mass and the waves of space-time emitted during t…

Exponential collapse with variable time scale driven by a scalar field
Jaime Mendoza Hernández, Mauricio Bellini, Claudia Moreno
We study the dynamic collapse driven by a scalar field, when a relativistic observer falls co-moving with the collapse and cross the horizon of a Schwarzschild black-hole (BH), at…
