Scale Length of Disk Galaxies

Kambiz Fathi, Mark Allen, Eduardo Gonzalez-Solares +2

As a part of a Euro-VO research initiative, we have undertaken a programme aimed at studying the scale length of 54909 Sa-Sd spiral galaxies from the SDSS DR6 catalogue. We have re…

Magnetic fields from inflation?

Vittoria Demozzi, Viatcheslav Mukhanov, Hector Rubinstein

We consider the possibility of generation of the seeds of primordial magnetic field on inflation and show that the effect of the back reaction of this field can be very important.…

Constraining dust and color variations of high-z SNe using NICMOS on Hubble Space Telescope

S. Nobili, V. Fadeyev, G. Aldering +24

We present data from the Supernova Cosmology Project for five high redshift Type Ia supernovae (SNe Ia) that were obtained using the NICMOS infrared camera on the Hubble Space Tele…

Strong Lensing by Subhalos in the Dwarf-Galaxy Mass Range II: Detection Probabilities

T. Riehm, E. Zackrisson, E. Mortsell +1

The dark halo substructures predicted by current cold dark matter simulations may in principle be detectable through strong-lensing image splitting of quasars on small angular scal…

Non-parametric foreground subtraction for 21cm epoch of reionization experiments

Geraint Harker, Saleem Zaroubi, Gianni Bernardi +12

An obstacle to the detection of redshifted 21cm emission from the epoch of reionization (EoR) is the presence of foregrounds which exceed the cosmological signal in intensity by or…

Do blue compact galaxies have red halos?

E. Zackrisson, G. Micheva, N. Bergvall +1

Red halos are faint, extended and extremely red structures that have been reported around various types of galaxies since the mid-1990s. The colours of these halos are too red to b…
