Intermediate-mass ratio inspirals in merging elliptical galaxies
Verónica Vázquez-Aceves, Pau Amaro Seoane, Dana Kuvatova +3
Close encounters between two initially unbound objects can result in a binary system if enough energy is released as gravitational waves (GWs). We address the scenario in which suc…
Triple path to the exponential metric
Maxim Makukov, Eduard Mychelkin
The exponential Papapetrou metric induced by scalar field conforms to observational data not worse than the vacuum Schwarzschild solution. Here, we analyze the origin of this metri…
The scalarized Raychaudhuri identity and its applications
Eduard G. Mychelkin, Maxim A. Makukov
We show that the covariant Raychaudhuri identity describing kinematic characteristics of space-time admits a representation involving a geometrical scalar which, depending on c…
Simpler than vacuum: Antiscalar alternatives to black holes
Maxim Makukov, Eduard Mychelkin
The Janis-Newman-Winicour and Papapetrou metrics represent counterparts to the Schwarzschild black hole with scalar and antiscalar background fields, correspondingly (where "anti"…
SETI in vivo: testing the we-are-them hypothesis
Maxim A. Makukov, Vladimir I. shCherbak
After it was proposed that life on Earth might descend from seeding by an earlier civilization, some authors noted that this alternative offers a testable aspect: the seeds could b…
Unified geometrical basis for the generalized Ehlers identities and Raychaudhuri equations
Eduard G. Mychelkin, Maxim A. Makukov
It is shown that the timelike, spacelike and null versions of the Ehlers identity, as well as ensuing Raychaudhuri equations, might be all derived within a single geometrical appro…
