Matching collapse and expansion across Matter Trapping surfaces in inhomogeneous CDM models
Alan Maciel, M. Le Delliou, José P. Mimoso
In the present work we examine the MTS, for the restriction to spherical dust plus , proving that it actually is a characteristic surface of the Cauchy problem (generated by its…
Comment on "Apparent horizons of the Thakurta spacetime and the description of cosmological black holes"
Alan Maciel, Vilson T. Zanchin
The findings discussed in "Apparent Horizons of the Thakurta Spacetime and the Description of Cosmological Black Holes" deviate from prior research, particularly our study in Phys.…
New insights on null and timelike warped symmetric spacetime splittings
Alan Maciel, Morgan Le Delliou, José P. Mimoso
We explore in detail the 2+2 and 1+1+2 formalism in spherically symmetric spacetimes, spanning from deducing the dynamical equations to relating them to the well-known generalised…
New perspectives on the TOV equilibrium from a dual null approach
Alan Maciel, Morgan Le Delliou, José P. Mimoso
The TOV equation appears as the relativistic counterpart of the classical condition for hydrostatic equilibrium. In the present work we aim at showing that a generalised TOV equati…
Charged cosmological black holes: a thorough study of a family of solutions
Daniel C. Guariento, Alan Maciel, Marina M. C. Mello +1
We study a class of charged cosmological black holes defined by the Shah-Vaidya solution, which is similar to the McVittie solution but for a central object of nonzero electric cha…
Revisiting the Birkhoff theorem from a dual null point of view
Alan Maciel, Morgan Le Delliou, José P. Mimoso
The Birkhoff theorem is a well-known result in general relativity and it is used in many applications. However, its most general version, due to Bona, is almost unknown and present…
