Summer jobs in the Division of Particle Physics and Astrophysics

The Division of Particle Physics and Astrophysics has strong theoretical and experimental research in its research fields.

Open positions for summer work include:

A) Experimental Particle Physics -Silicon sensor development: The CMS Upgrade project of Helsinki Institute of Physics (HIP) is looking for a summer trainee to assist in laboratory measurements. He/she will participate in semiconductor sensor characterization in the Physics Department/HIP Detector Laboratory premises in Kumpula/Physicum. The summer assignment consists of capacitance-voltage (CV), leakage current (IV) and Transient Current Technique (TCT) measurements. Previous experience is not required, but systematic practices in experimental work and Matlab skills are an asset for the candidate.

B) The Euclid project has open paid summer trainee positions for physics, theoretical physics, and astronomy students. The position is for three months in May-August (the exact dates to be agreed). The work is related to the Finnish Euclid Science Data Center (simulating and analyzing Euclid data) and/or the physics of the expanding universe and dark energy. The work involves study of some of these topics, and related tasks suitable for the student's level. Working on a Bachelor's or Master's thesis can be included. A good study record and computer skills (e.g., Unix, C, C++) are important. It would be good if the student has taken at least some of the courses Cosmology I, Cosmology II, and General Relativity; but this is not a necessary requirement, if the student is able to learn required material before or during the summer position.

Euclid is the next European Space Agency cosmology satellite, to be launched in March 2020. It will photograph over one third of the sky in visible and near-infared wavelengths, obtaining images of over a billion galaxies and spectra of tens of millions of galaxies. Using the redshifts of galaxies and the distortion of galaxy images caused by gravitational lensing by the intervening matter, Euclid will produce a 3-dimensional map of the distribution of visible and dark matter over a sizable part of the observable universe. The main goal of Euclid is to help solve the Dark Energy Problem: What is causing the acceleration of the expansion of the universe - is it a new form of energy, called dark energy, or does gravity deviate at cosmological distances from Einstein's theory of General Relativity. Finland provides one of the nine Euclid Science Data Centers, the SDC-FI. This is currently based on virtual machines running on CSC's Pouta Cloud Service. We participate in producing simulated Euclid data and in developing data analysis methods for Euclid.

D) Summer jobs in Theoretical Extragalactic research:

We are looking for summer trainees with a background in astrophysics and/or theoretical physics combined with good programming skills to join the Theoretical Extragalactic research group for a three month period over the summer. The research topics on offer include:

1) Visualization and movie making: Researchers in the group conduct numerical simulations of galaxy mergers, cosmological simulations of galaxy formation and adaptive-mesh simulations of the formation of the first supermassive black holes in the Universe. The job of the trainee would be to analyse and visualize the simulation outputs and then as an end product make movies that help in interpreting the astrophysical phenomena.

2) The astrophysics of galaxy formation: In this project the trainee will run their own numerical galaxy simulations and study in detail the impact of various astrophysical processes, such as gas cooling, star formation, supernova feedback and supermassive black holes. The aim is to understand the relative importance of the various astrophysical processes as a function of galaxy mass, from dwarf galaxies to giant galaxies.
