Free-Form and Hybrid Lens Models for SDSS J1004+4112: Substructure and Central Image Time Delay Constraints
Derek Perera, Liliya L. R. Williams, Jori Liesenborgs +2
SDSS J1004+4112 is a well studied gravitational lens with a recently measured time delay between its first and fourth arriving quasar images. Using this new constraint, we present…
Wave Mechanics, Interference, and Decoherence in Strong Gravitational Lensing
Calvin Leung, Dylan Jow, Prasenjit Saha +3
Wave-mechanical effects in gravitational lensing have long been predicted, and with the discovery of populations of compact transients such as gravitational wave events and fast ra…
Wave optics of the solar gravity lens
Sara Engeli, Prasenjit Saha
It is well known that the solar gravitational field can be considered as a telescope with a prime focus at locations beyond 550 au. In this work we present a new derivation of the…
Simulations of astrometric planet detection in Alpha Centauri by intensity interferometry
Km Nitu Rai, Subrata Sarangi, Prasenjit Saha +1
Recent dynamical studies indicate that the possibility of an Earth-like planet around Cen A or B should be taken seriously. Such a planet, if it exists, would perturb the orbi…
Radius measurement in binary stars: simulations of intensity interferometry
Km Nitu Rai, Soumen Basak, Prasenjit Saha
Mass and radius measurements of stars are important inputs for models of stellar structure. Binary stars are of particular interest in this regard, because astrometry and spectrosc…
Observed versus Simulated Halo c-Mvir Relations
Dominik Leier, Ignacio Ferreras, Andrea Negri +1
The concentration - virial mass relation is a well-defined trend that reflects the formation of structure in an expanding Universe. Numerical simulations reveal a marked correlatio…
