DAWN Alumni

Carlos Gómez-Guijarro receiving his PhD at DAWN in the spring of 2019

This page is dedicated to the people who have graduated as MSc or PhD from DAWN, or people who have in other ways spend significant amounts of time at DAWN.

PhD graduates

Carlos Gómez-Guijarro
PhD | The Cosmic Dawn Center (DAWN)
Niels Bohr Institute, University of Copenhagen

I am a PhD graduate from the Cosmic Dawn Center advised by Sune Toft. My research focuses on galaxy formation and evolution across the history of the Universe. I am interested in the evolutionary pathways of massive galaxies. Particularly, the nature and role of dusty star-forming galaxies as their progenitors, how and what made star-forming galaxies to stop forming stars. I use observations from X-rays to radio wavelengths from both space and the ground.
Before coming to Copenhagen for my PhD I was a student at the Complutense University of Madrid, where I received my Bachelor and Master degrees in Physics and Astrophysics and started my scientific career. I did internships as a summer student at the Instituto de Astrofísica de Canarias (IAC, Spain) and the Instituto de Radioastronomía y Astrofísica (IRyA, Mexico). During my PhD I have also worked closely with scientists at the Argelander-Institut für Astronomie (AIfA, Germany) and Cornell University (USA), where I spent a few months.

Mikkel Stockmann
PhD | The Cosmic Dawn Center (DAWN)
Niels Bohr Institute, University of Copenhagen

I am a Danish PhD graduate from the Cosmic Dawn Center, after starting my PhD at the Dark Cosmology Centre under the Supervision of Sune Toft. My main research has been concentrated on the evolution of massive galaxies and their death across the last 10 billion years.

I utilized the Danish build X-Shooter instrument attached to the Very Large Telescope located in Paranal, Chile for my thesis. Together with time granted on the prestigious Hubble Space Telescope I have studied the structural properties and stellar populations of the largest sample of massive quiescent galaxies at z>2.  In a closely related project, I was awarded additional time with X-Shooter, to study these massive dead galaxies with very high resolution by taking advantage of the beautiful effect called gravitational lensing.  I take part in public outreach both via Astronomy On Tap events and popular scientific talks.

Outside astronomy I like to rock climb and enjoy the cultural life of Copenhagen.

I was awarded my doctorate degree after successfully defending my thesis on the 23rd of October.


MSc graduates

Cecilie S. Nørholm
MSc| The Cosmic Dawn Center (DAWN)
Niels Bohr Institute, University of Copenhagen

I am a MSc graduate from the Cosmic Dawn Center, advised by Francesco Valentino, Georgios Magdis, and Sune Toft. My thesis was on environmental effects on galaxy evolution, where I am investigating galaxies in clusters and protoclusters through data obtained with the Very Large Telescope. I obtained my Bachelor’s degree in 2017, also at the University of Copenhagen, with Marianne Vestergaard as supervisor.

I enjoy being able to work with observational data, which was something I first experienced in 2016. Here, I attended a course on observational astronomy where I, together with a group of fellow students, planned and executed observations at the Nordic Optical Telescope.

When not working, I am very interested in communication of science, which I enjoy doing through my student job at the Tycho Brahe Planetarium as well as by giving lectures to secondary school students attending internships at University of Copenhagen.

Christina Konstantopoulou
MSc| The Cosmic Dawn Center (DAWN)
Niels Bohr Institute, University of Copenhagen

I am a MSc graduate from the the Cosmic Dawn Center supervised by Johan Peter Uldall Fynbo. I received my Bachelor degree in 2017 from the University of  Patras. My master’s thesis focuses on red quasars, and the aim is to characterize the efficiency of quasar selection based on astrometry, which does not suffer from most of the selection biases of other existing methods. Direct observations are obtained with the Nordic Optical Telescope (NOT) and astrometry is provided by the ESA Gaia mission.

I completed my internship at the Institute for Astronomy, Astrophysics, Space Applications and Remote Sensing (IAASARS), National Observatory of  Athens, supervised by Vassilis Charmandaris.

Ivanna Langan
MSc Intern | The Cosmic Dawn Center (DAWN)

Université Pierre-et-Marie-Curie, Paris
I am a French master's degree student coming from La Sorbonne, in Paris. I did a 3 months internship at DAWN, advised by Daniel Ceverino. We studied the properties of the first galaxies simulated by Daniel Ceverino's FirstLight project, trying to make predictions which will be tested by future telescopes.
Besides astrophysics, I love to travel the world, discover new cultures and languages, hence my bachelor's degree in physics and Chinese which enabled me to spend half of last year mostly in Taiwan. I also learned to play the piano at the conservatoire from the age of 6 until last year.

Former scientific employees

Jonatan Selsing
Postdoc | The Cosmic Dawn Center (DAWN)
Current employer: Novo Nordisk

I am a postdoctoral researcher at the Cosmic Dawn Center employed under a DFF grant to D. Watson. I received my PhD degree in 2018 from the Dark Cosmology Centre under the supervision of Dr. Lise Christensen. My research is centered around the transient universe and how these events shape the cosmochemical evolution history of our Universe.

I have made conclusive contribution to the discovery that was named the Science Breakthrough of the year 2017, and continue to play an important role in the follow-up of gravitational wave counterparts through my role as instrument specialist in the ENGRAVE consortium. Additional to my strong interest in the gravitational wave counterparts, I take an active part in the follow-up of Gamma-Ray Bursts, where I use facilities in both Chile under ESO, but also on La Palma at the NOT telescope. I regularly give public outreach talk to the public and produce to popular scientific magazines.
Outside academia, I am married to Malene. Together we have Marie and Ellen, our two wonderful daughters.
