Measuring the halo mass of z similar to 3 damped Ly alpha absorbers from the absorber-galaxy cross-correlation
high-redshift absorption lines
2014/12/24
We test the reliability of a method to measure the mean halo mass of absorption-line systems such as damped Lyα absorbers (DLAs). The method is based on measuring the ratio of the cross-correlation be...
I review measurements of star formation in nearby galaxies in the UV-to-FIR wavelength range, and discuss their impact on SFR determinations in intermediate and high redshift galaxy populations. Exist...
I review measurements of star formation in nearby galaxies in the UV-to-FIR wavelength range, and discuss their impact on SFR determinations in intermediate and high redshift galaxy populations. Exist...
We present a method for investigating variations in the upper end of the stellar initial mass function (IMF) by probing the production rate of ionizing photons in unresolved, compact star clusters wit...
Measuring a cosmological distance-redshift relationship using only gravitational wave observations of binary neutron star coalescences
neutron stars gravitational waves cosmology
2011/10/14
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...
