Recent rapid progress in time domain surveys makes it possible to detect various types of
explosive transients in the Universe in large numbers, some of which will be gravitationally …

The cold dark-matter model successfully explains both the emergence and evolution of
cosmic structures on large scales and, when we include a cosmological constant, the …

We present a physically motivated model for the early coevolution of massive spheroidal
galaxies and active nuclei at their centers. Within dark matter halos, forming at the rate …

Abstract The Sloan Lens ACS (SLACS) Survey is an efficient Hubble Space Telescope
(HST) Snapshot imaging survey for new galaxy-scale strong gravitational lenses. The …

We show how observations of multiply imaged quasars at high redshift can be used as a
probe of dark matter clumps (subhalos with masses≲ 10 9 M⊙) within the virialized extent of …

We study the constraints that high-redshift structure formation in the universe places on
warm dark matter (WDM) dominated cosmological models. We modify the extended Press …

Fast radio bursts (FRBs), bright transients with millisecond durations at∼ GHz and typical
redshifts probably> 0.8, are likely to be gravitationally lensed by intervening galaxies. Since …

Recent high-resolution N-body CDM simulations indicate that nonsingular three-parameter
models such as the Einasto profile perform better than the singular two-parameter models …

The statistics of gravitationally lensed arcs was recognized earlier as a potentially powerful
cosmological probe. However, while fully numerical models find orders of magnitude …

Strong gravitational lensing effect is a powerful tool to probe cosmological models and
gravity theories. Recently, the time-delay cosmography from strong lensing and the stellar …
