Fynbo, Johan P. U., Prochaska, J. Xavier, Sommer-Larsen, Jesper, Dessauges-Zavadsky, Miroslava, Moller, Palle
We test the hypothesis that the host galaxies of long-duration gamma-ray bursts (GRBs) as well as quasar-selected damped Lyman-alpha (DLA) systems are drawn from the population of UV-selected...
An on-going multi-wavelength survey of Ly-alpha emitters at redshifts z = 2 - 8 (2006)
Nilsson, Kim K., Fynbo, Johan P. U., Moller, Palle, Orsi, Alvaro
In the last decade, the technique of finding Ly-alpha emitters through narrow-band imaging has become a promising method of detecting high redshift galaxies. Ly-alpha emitters have been found from...
Three intervening galaxy absorbers towards GRB060418: faint and dusty? (2006)
Ellison, Sara L., Vreeswijk, Paul, Ledoux, Cedric, Willis, Jon P., Jaunsen, Andreas, ...
We present an analysis of three strong, intervening Mg II absorption systems (z_abs = 0.603, 0.656, 1.107) towards the optical afterglow of gamma-ray burst (GRB) 060418. From high resolution UVES...
Nilsson, Kim, Fynbo, Johan P. U., Moller, Palle, Sommer-Larsen, Jesper, Ledoux, Cedric
We report on the discovery of a z = 3.16 Lyman-alpha emitting blob in the GOODS South field. The blob has a total Ly-alpha luminosity of ~ 10^(43) erg s^(-1) and a diameter larger than 60 kpc. The...
The Lyman-alpha glow of gas falling into the dark matter halo of a z=3 galaxy (2004)
Weidinger, Michael, Moller, Palle, Fynbo, Johan P. U.
Quasars are the visible signatures of super-massive black holes in the centres of distant galaxies. It has been suggested that quasars are formed during ``major merger events'' when two massive...
GRB 020410: A Gamma-ray burst afterglow discovered by its supernova light (2004)
Levan, Andrew, Nugent, Peter, Fruchter, Andrew, Burud, Ingunn, Branch, David, Rhoads, James, ...
We present the discovery and monitoring of the optical transient (OT) associated with GRB 020410. The fading OT was found by Hubble Space Telescope (HST) observations taken 28 and 65 days after burst...
Optical Photometry of GRB 021004: The First Month (2002)
Holland, Stephen T., Weidinger, Michael, Fynbo, Johan P. U., Gorosabel, Javier, Hjorth, Jens, Pedersen, Kristian, ...
We present U,B,V,R_C,and I_C photometry of the optical afterglow of the gamma-ray burst GRB 021004 taken at the Nordic Optical Telescope between approximately eight hours and 30 days after the burst....
Discovery of the optical counterpart and early optical observations of GRB 990712 (2000)
Sahu, Kailash C., Vreeswijk, P. M., Bakos, Gaspar A., Menzies, John W., Bragaglia, Angela, Frontera, Filippo, ...
We present the discovery observations of the optical counterpart of the gamma-ray burst GRB 990712 taken 4.16 hr after the outburst and discuss its light curve observed in the V, R, and I bands...
Discovery of the optical counterpart and early optical observations of GRB 990712 (2000)
Sahu, Kailash C., Vreeswijk, P. M., Bakos, Gaspar A., Menzies, John W., Bragaglia, Angela, Frontera, Filippo, ...
We present the discovery observations of the optical counterpart of the gamma-ray burst GRB 990712 taken 4.16 hr after the outburst and discuss its light curve observed in the V, R, and I bands...
HST Images of a Galaxy Group at z=2.81, and the Sizes of Damped Lyman Alpha Galaxies (1998)
Moller, Palle, Warren, Stephen J.
We present HST WFPC2 observations in three bands (F450W, F467M and F814W) of a group of three galaxies at z=2.8 discovered in a ground-based narrow-band search for Lyman alpha emission near the z=2.8...
On the nature of z(abs) ~ z(em) damped absorbers in quasar spectra (1997)
Moller, Palle, Warren, Stephen J., Fynbo, Johan U.
We present spectroscopic observations of the damped Ly-alpha absorber at redshift z=1.9342 seen in the spectrum of the quasar Q0151+048A. The redshift of the absorber is greater than the redshift of...
A Group of Galaxies at Redshift 2.38 (1995)
Francis, Paul, Woodgate, Bruce, Warren, Steve, Moller, Palle, Mazzolini, Marg, Bunker, Andy, ...
We report the discovery of a group of galaxies at redshift 2.38. We imaged about 10% of a claimed supercluster of QSO absorption-lines at z=2.38 (Francis & Hewett 1993). In this small field (2 arcmin...
