SOFIA webinar

May 27 2022

I am giving an online talk at the SOFIA Summer Series 2022 that consists of five webinar talks on “Synergies within the Infrared Archive”. My talk is on Friday, May 27 at 9 am PDT (6 pm CET), and it will be recorded and available later on SOFIA YouTube channel. As CARS is a multiwavelength survey, I will present how we used SOFIA data and what synergies worked out for CARS. [Read More]

SOFIA Tele-talk

I gave the SOFIA Tele-talk on Wednesday, November 20 at 6 pm (Central European Time). It was recorded and is available here.

The schedule page with other talks and recordings is here.

You can also sigh up for the Science e-Newsletter to receive e-mails with recent scientific results made with SOFIA. Check out the example of such an e-Newsletter with my work highlighted in it!

SOFIA Cycle 5

July 19-31 2017, Christchurch, New Zealand

SOFIA is the Stratospheric Observatory for Infrared Astronomy with a Hubble-sized telescope onboard a modified Boeing 747SP. SOFIA combines features of a space and a ground-based observatory: observing from the stratosphere SOFIA does not have a limit on the number of instruments and can also be upgraded through time. I was very lucky to participate the SOFIA Cycle 5 flights in July 2017 from Christchurch, New Zealand. With the Far Infrared Field-Imaging Line Spectrometer (FIFI-LS) we observed [CII] emission line map of an AGN host galaxy HE 2211-3903. [Read More]


Processing extragalactic observations

The FIFI-LS team provides science-ready data reduced with the standard pipeline, but the output datacube often does not contain any useful information for the faint sources. The low signal-to-noise data should be treated differently in order not to lose any information. I have modified the last steps of the reduction based on the Drizzle algorithm and managed to derive the datacubes with more reasonable spaxel size. With this new technique we discovered the strongest [CII] excess observed so far at low redshift. [Read More]
