Comments on "Derivation of the Raychaudhuri Equation" by Dadhich
Abhas Mitra
In a recent preprint, gr-qc/0511123, Dadhich has given a brief yet beautiful exposition on some of the research works by Prof. A.K. Raychaudhuri. Here Dadhich highlights the fact t…
Why the observed black hole candidates do not show spin pulsation
Abhas Mitra
It is shown here that the so-called spinning Black Hole Candidates (BHCs) cannot be Black Holes (BHs) at all and, on the other hand, must be spinning hot Eternally Collapsing Objec…
On the non-occurrence of Type I X-ray bursts from the Black Hole Candidates
Abhas Mitra
It has been justifiably questioned that if the Black Hole Candidates (BHCs) have a ``hard surface'' why Type I X-ray bursts are not seen from them (Nayayan, R., Black Holes in Astr…
Magnetospheric Eternally Collapsing Objects (MECOs): Likely New Class of Source of Cosmic Particle Acceleration
Abhas Mitra
It is known that spinning pulsars could be source of VHE-UHE cosmic particle acceleration. It is also conjectured that (fictitious) spinning Black Holes (BH) could be sites of cosm…
On the Probable Nature of the "Dark Particle Accelerators" Discovered by HESS
Abhas Mitra
We estimate that the vacuum electric field associated with a spinning Magnetospheric Eternally Collapsing Object MECO (www.phys.uni-sofia.bg/~astro/abbrev.html) could be higher by…
Comments on the proposal of Dark Energy Stars by Chapline
Abhas Mitra
We point out that the contentions of Chapline (astro-ph/0503200)[1] that (i) General Relativity (GR) is in conflict with Quantum Mechanics (QM) and (ii) GR fails even on macroscopi…
