Obscuration and confusion conspire to limit our knowledge of the inner Milky Way. Even at moderate distances, the identification of stellar systems becomes...
A Maximum Likelihood Method for Bidimensional Experimental Distributions and Its Application to the Galaxy Merger Fraction
The determination of the galaxy merger fraction of field galaxies using automatic morphological indices and photometric redshifts is affected by several biases...
The exceptionally high luminosities of gamma-ray bursts (GRBs), gradually emerging as extremely useful probes of star formation, make them promising tools for...
A measurement at the first acoustic peak of the cosmic microwave background with the 33-GHz interferometer
This paper presents the results from the Jodrell Bank-Instituto de Astrofisicia de Canarias (IAC) two-element 33-GHz interferometer operated with an element...
A measurement of galaxy halo mass from the surrounding H I Lyα absorption
We measure the dark matter halo masses of ≈ 2.36 UV colour-selected star-forming galaxies by matching the observed median H I Lyα absorption around them, as...
A measurement of the background solar velocity spectrum
Ten years of continuous measurements of the radial velocity of the Sun have been used to estimate the contribution of various solar surface phenomena to the...
A Measurement of the Galactic Rotation in the 4TH Quadrant
Using the VLA and the VLBA we have observed water maser emission in the proto-planetary nebula candidate IRAS 19134+2131, in which the water maser spectrum has...
A measurement of the I = I solar rotational splitting
A precise measurement of the l = 1 rotational splitting has been derived from the 1991 IRIS data and it leads to a moderate rotation rate in the solar core.
A meta-analysis of the magnetic line broadening in the solar atmosphere
A multiline Bayesian analysis of the Zeeman broadening in the solar atmosphere is presented. A hierarchical probabilistic model, based on the simple but...
