For the first time, astronomers have pinpointed the location in the sky of a Fast Radio Burst (FRB), allowing them to determine the distance and home galaxy of one of these mysterious pulses of radio ...
We discovered a large-scale shell G53.9+0.2 around the Crab-like pulsar wind nebula (PWN) G54.1+0.3 with 1420 MHz continuum Very Large Array observations. This is confirmed by a new infrared (IR) imag...
Scientists on the world's longest-distance neutrino experiment announced today that they have seen their first neutrinos.
Detection of gravitational waves from the inspiral phase of binary neutron star coalescence will allow us to measure the effects of the tidal coupling in such systems. These effects will be measurable...
We describe a new formalism to fit the parameters $\alpha$ and $\beta$ that are used in the SALT2 model to determine the standard magnitudes of Type Ia supernovae. The new formalism describes the intr...
We apply the method of Burnett & Binney (2010) for the determination of stellar distances and parameters to the internal catalogue of the Radial Velocity Experiment (Steinmetz et al. 2006). Subsamples...
The classical method for measure the Earth-Sun distance is due to Aristarchus and it is based upon the measure of the angle Moon-Earth-Sun when the Moon is exactly in quadrature. Such an angle is only...
The orbit and distance of WR140     orbit  distance of WR140       2010/11/10
A campaign of 35 epochs of milli-arcsecond resolution VLBAobservations of the archetype collidingwind WR+O star binary system WR140 show the wind-collision region (WCR) as a bow-shaped arc of emission...
Cosmological observations indicate that our universe is flat and dark energy (DE) dominated at present. The luminosity distance plays an important role in the investigation of the evolution and stru...
There is a growing community of astronomers presenting evidence that the pulsar wind nebula 3C58 is much older than the connection with the historical supernova of A.D 1181 would indicate. Most of the...
The absence of guidance from fundamental physics about the mechanism behind cosmic acceleration has given rise to a number of alternative cosmological scenarios.
The proximities are important for di®erent purposes, for example to evaluate the risk of collisions of asteroids or comets with the Solar-System planets. We describe a simple and e±cient method fo...
In this paper, we consider a statistical method for distance determination of stellar groups. The method depends on the assumption that the members of the group scatter around a mean absolute magnitud...
Using the European Southern Observatory´s Very Large Telescope (VLT), astronomers from the University of Sheffield have detected a stellar mass black hole much farther away than any other previo...
Inhomogeneous cosmological models have had significant success in explaining cosmological observations without the need for dark energy. Generally, these models imply inhomogeneous matter distribution...
