The Valparaíso ALMA Line Emission Survey

Posted on 14/02/2017 by Tom

During my time in Chile, I’ve been working on a new survey. The Valparaíso ALMA Line Emission Survey (VALES) is a sample of main-sequence and starburst galaxies selected from the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS). The idea is … Read more →

Stacking optical spectra of galaxies

Posted on 30/10/2014 by Tom

Here’s a short animation showing the effects of stacking up spectra. Measuring the intensities and equivalent widths of emission lines can be tricky in galaxy spectra where the signal-to-noise (S/N) is low, mostly due to difficulty in determining the baseline … Read more →

Galaxies in 3D across the Universe

Posted on 08/07/2014 by Tom

Nearby galaxy studies are increasingly shifting from using global, integrated measurements to spatially-resolved observations available thanks to technological improvements in IFU 3D-spectroscopy and radio interferometry. We’re into the second day of the IAU Symposium 309, Galaxies in 3D across the … Read more →

Gas properties from Herschel FIR spectroscopy

Posted on 20/05/2014 by Tom

I’ve had a great time studying how far-infrared (FIR) lines probe interstellar gas properties. This week, I attended the 69th Dutch Astronomy Conference, held in Noordwijkerhout, The Netherlands. I presented a poster based on the latest work from my next … Read more →
