arXiv:1302.2623 by: Rauch, Michael Abstract: In this third paper in a series on the nature of extended, asymmetric Lyman alpha emitters at z ~ 3 we report the discovery, in an ultra-deep, blind, spectroscopic long-slit survey, of a Lyman alpha emitting...

We investigate the origin of extragalactic continuum emission and its relation to the stellar population of a recently discovered peculiar z=3.344 Lyman alpha emitter. Based on an analysis of the broad-band colors and morphology we find further support...

Countdown to PSLV-C37 launchCountdown The Indian Space Research Organisation (Isro) plans to set a world record by launching 104 satellites on board a Polar Satellite Launch Vehicle (PSLV) flight on 15 February. It will be the thirty ninth flight of...

Using wide field narrow-band surveys, we provide a new measurement of the $z=6.6$ Lyman-$\alpha$ Emitter (LAE) luminosity function (LF), which constraints the bright end for the first time. We use a combination of archival narrow-band NB921 data in UDS...
