TalkCosmology on small scales: the structure of (mostly) dark matter halos
The standard model of cosmology -- the ``Lambda cold dark matter'' model -- is based on the idea that the dark matter is a collisionless elementary particle...

PublicationDensity weighted angular redshift fluctuations: a new cosmological observable
We propose the use of angular fluctuations in the galaxy redshift field as a new way to extract cosmological information in the Universe. This new probe $\delta...

PublicationDetection of Gravitational Redshift in Open Cluster Nondegenerate Stars
A key observational prediction of Einstein's Equivalence Principle is that light undergoes redshift when it escapes from a gravitational field. Although...

PublicationDwarf Galaxies with Central Cores in Modified Newtonian Dynamics Gravity
Some dwarf galaxies are within the Mondian regime at all radii, i.e., the gravitational acceleration provided by the observed baryons is always below the...

PublicationExtremely fast orbital decay of the black hole X-ray binary Nova Muscae 1991
We present new medium-resolution spectroscopic observations of the black hole X-ray binary Nova Muscae 1991 taken with X-Shooter spectrograph installed at the 8...

PublicationFast orbital decays of black hole X-ray binaries: XTE J1118+480 and A0620-00★
We present new 10.4 m-GTC/OSIRIS spectroscopic observations of the black hole X-ray binary XTE J1118+480 that confirm the orbital period decay at dot{P}=-1.90±...

PublicationForce equation of the large-scale structure of the Universe.
This article presents a statistical-mechanical treatment of a relationship (the force equation) between the gravitational potential for two particles and the...

PublicationFormation of Slowly Rotating Elliptical Galaxies in Major Mergers. A Resolution Study
We study resolution effects in numerical simulations of gas-rich (20% of the total baryonic mass) major mergers, and show that the formation of slowly-rotating...
