The galaxies in the field of the nearby GRB980425/SN1998bw

S. Foley, D. Watson, J. Gorosabel +5

We present spectroscopic observations of ESO 184-G82, the host galaxy of GRB980425/SN1998bw, and six galaxies in its field. A host redshift of z=0.0087+/-0.0006 is derived, consist…

Supernova Cosmology and the ESSENCE project

Jesper Sollerman, Claudio Aguilera, Andy Becker +27

The proper usage of Type Ia supernovae (SNe Ia) as distance indicators has revolutionized cosmology, and added a new dominant component to the energy density of the Universe, dark…

Outshining the quasars at reionisation: The X-ray spectrum and lightcurve of the redshift 6.29 Gamma-Ray Burst GRB050904

D. Watson, J. N. Reeves, J. Hjorth +7

Gamma-ray burst (GRB) 050904 is the most distant X-ray source known, at z=6.295, comparable to the farthest AGN and galaxies. Its X-ray flux decays, but not as a power-law; it is d…

Hubble Space Telescope Observations of Nine High-Redshift ESSENCE Supernovae

Kevin Krisciunas, Peter M. Garnavich, Peter Challis +29

We present broad-band light curves of nine supernovae ranging in redshift from 0.5 to 0.8. The supernovae were discovered as part of the ESSENCE project, and the light curves are a…

GRB 050509B: Constraints on short gamma-ray burst models

J. Hjorth, J. Sollerman, J. Gorosabel +19

We have obtained deep optical images with the Very Large Telescope at ESO of the first well-localized short-duration gamma-ray burst, GRB 050509B. From V and R imaging, initiated ~…

The GRB 030329 host: a blue low metallicity subluminous galaxy with intense star formation

J. Gorosabel, D. Pérez-Ramírez, J. Sollerman +13

We present broad band photometry and spectroscopic observations of the host galaxy of GRB 030329. Analysis of the spectral emission lines shows that the host is likely a low metall…
