The WISP survey: overview of recent results for galaxies in the 1

The WFC3 Infrared Spectroscopic Parallel Survey (WISP) is a large ( ~1000 orbits) HST program that uses WFC3 slitless spectroscopy to detect thousands of galaxies across a wide redshift range 0.3 < z < 2.3. I will present an overview of recent results on emission line galaxies, including a statistical determination of their dust extinction properties, the discovery of a new population of extremely strong emission-line dwarf galaxies, and the implication of the observed number counts for the EUCLID mission. I will also discuss the properties of passive galaxies at z~1.5 derived from the combination of the WISP spectra with broad-band photometry from HST-UVIS and Spitzer images.
