The ALMA Protostellar Interferometric Line Survey (PILS)

Exploring the origin of complex organic molecules in star forming regions

About PILS

Welcome to the website of the ALMA Protostellar Interferometric Line Survey (PILS). The aim of PILS is to investigate the origin of complex organic molecules seen toward nearby star forming regions. PILS consists of an unbiased line survey of the protostellar binary IRAS 16293-2422 using ALMA. The PILS data cover the full atmospheric window at 0.8 mm (the spectral window from 329 to 363 GHz) with a spectral resolution of 0.2 km/s and full imaging at 0.5 arcsecond angular resolution (60 AU).

Team

The members of the PILS team are Jes Jørgensen (PI), Matthijs van der Wiel, Audrey Coutens, Julie Lykke, Holger Müller, Ewine van Dishoeck, Hannah Calcutt, Per Bjerkeli, Tyler Bourke, Maria Drozdovskaya, Edith Fayolle, Rob Garrod, Steffen Jacobsen, Niels Ligterink, Karin Öberg, Magnus Persson, Susanne Wampfler, Nadia Murillo, Gwendoline Stephan, Sebastien Manigand & Eric Willis
