Research opportunities: 

 are many opportunities for bachelor projects , or summer internships. Let's chat! 

During my position at Leiden Observatory, I was privileged to supervise some amazing students from around the world on original research projects!

Past Members: 

Stefan van der Giessen
Stefan is interested in the evolution of galaxy properties with redshift. For his first-year masters project (in 2019/2020) at Leiden University he studied the variation of dust attenuation in star-forming galaxies at redshift z~0 selected from the SDSS and GAMA survey and at z~0.7 from the COSMOS survey. He compared observed UV-NIR magnitude-inclination relations with an attenuation-inclination model described in Tuffs et al.(2004) to constrain optical depths and clumpiness of the dust as a function of galaxy properties. His results can be found in this A&A article!  In September 2021, Stefan started his PhD position at Ghent University, studying interstellar dust with Ilse De Looze. 

Shravya Shenoy (Leiden University)
For Shravya's first-year masters project at Leiden University, she worked with multi-wavelength data to understand the relationship between radio luminosity at low frequencies and galaxy star-formation rates (SFR) in the local universe (z<0.2). By applying machine learning algorithms on a large statistical sample of LOFAR and GALEX-SDSS-WISE data, Shravya’s research looks at which other galaxy parameters affect the radio-SFR relation and why.

Joppe Swart

For Joppe's first year master project at Leiden University, he worked to detect free-free emission in high-redshift  (0.6<z<1.5) star forming galaxies.  He reduced and imaged 22 GHz data from the Very Large Array and combined this with existing radio continuum observations to model the radio spectra and measure free-free emission star formation rates of three bright galaxies in COSMOS field.

Hamid Hassani (SBU/IPM, Iran)

Hamid is an expert in radio continuum emission in nearby star-forming galaxies. In summer 2021, Hamid was a LEAPS summer intern, working with me to determine the average extra-planar extent of radio continuum emission at 150 MHz using the LOFAR survey. Hamid developed an image stacking analysis method to detect the faint emission from the galaxy halos.  Hamid is now a PhD candidate at the University of Alberta, working with Dr. Erik Rosolowsky.

Evie Makroleivaditi (University of Bonn).

Evie is an Astronomy masters student at the University of Bonn and the Max Planck Institute for Radio Astronomy.  In the summer of 2021, Evie  worked with me as a LEAPS summer intern, investigating the molecular gas content of radio-loud active galactic nuceli. Evie reduced IRAM 30m observations of the CO(1-0) line in 17 MaNGA galaxies with radio-loud AGN. Evie recently presented her results in a poster at the 1st KIAA Forum on Gas in Galaxies for Early Career Scientists. Evie now works at 

Celia Mulcahey

Celia completed their undergraduate studies at Mt Holyoak majoring in Astronomy & Geology. In the summer of 2020, Celia was a LEAPS summer intern working on the "Star formation and AGN feedback in the local universe: insights from optical integral field spectroscopy and radio continuum". Since then we have continued working with radio data from LoTSS and MaNGA to study star formation and stellar populations in a sample of radio-selected AGN. Celia presented a poster at the AAS 237 meeting on this work, and the manuscript was published in A&A . For this work, Celia was awarded Mary Daily Irvine Prize for the most outstanding thesis in the five college consortium. 

Celia is now an astrophysics graduate student at the Johns Hopkins University and a researcher at the Space Telescope Science Institute.
