Johannes Spreeuw - Previously I worked on neutron star-neutron star binaries at the University of Amsterdam and on microlensing events at Columbia University. After that I worked in finance for several years. Now I am trying to move back into astronomy, so I was very happy to be accepted for summer school at Astron. Particularly, because the topic of my research is so interesting, I am working on data from the Initial Test Station of Lofar with Ger de Bruyn. The pictures should show Jupiter as a strong radio source. Possibly, with high time resolution at long wavelengths, we can examine accurately the outbursts caused by Jupiter's moon Io. Heino Falcke and Lars Bahren have started a collaboration with a French group at Nancay, I might be able to contribute to that and/or design new measurements of the Initial Test Station, involving polarization measurements.

Bi-Qing For - I come from Malaysia. I just completed my third year as an undergraduate in astronomy and physics at the University of Arizona, U.S.A.. With the guidance of my supervisor, Willem van Straten, I am reducing and calibrating WSRT observation of pulsar (PSR J0218+4232) data. The final goal of this project is to model J0218+4232 pulsar with rotating vector model (RVM).

Kalle Torstensson - I received my masters degree from Chalmers University of Technology this spring, John Black supervised my thesis "Radio Aeronomy of Planetary Satellites: Io". After summer I will go to the NOT (Nordic Optical Telescope) for a one year studentship.
I am working for Klockner & Hagiwara on EVN (18cm continuum) data of the galaxy NGC 7469, possibly more sources will follow. Our hope is to find (clusters of) young SNRs in the starburst nuclei of the galaxy and probe the compact radio core.

Carmen Blasco - My name is Cramen Blasco and I come from Spain. My advisors are Hayley Bignall, Huib Jan van Langevelde and Cormac Reynolds. I am working with VLBA data to study the radiation coming from distant quasars. This radiation comes through a galaxy different from our own before it reaches us, being scattered.

Monica Orienti - I am Monica Orienti and I come from Bologna where I am a PhD student. As summer student at JIVE, I am working with Mike Garrett, Cormac Reynolds and Zsolt Paragi on projects related to Wide-Field Imaging Simulations, "Full Beam" Self Calibration techniques and on the FIR-radio correlation. The simulation project attempts to measure the dynamic range limitations introduced in VLBI imaging, by averaging the response of many faint sources that lie within the primary beam of each antenna, in addition of the target source. The second project will attempt to "self calibrate" real VLBI data using the main faint sources that fall within the primary beam of the antennas. the goal is to demonstrate that by using "wide-field" self calibration techniques, any part of the low frequency sky (<2 GHz) can be observed. For the third project, the aim is to verify if it is possible to estimate redshift for the sources via tge FIR-radio correlation. To do this, we are cross-correlating the Westerbork 1.4 GHz deep survey and the Spitzer First Look Survey (verification region), using 24, 70 and 160 microm data.

Tobias Westmeier - My name is Tobias Westmeier. I am in the first year of my PhD thesis at the Radioastronomical Institute of the University of Bonn in which I investigate Compact High-Velocity Clouds in the Milky Way and in M31. I am mainly observing these clouds in HI using the Effelsberg telescope. My work in the summer student programme is closely related to the topic of my PhD thesis. Under the supervision of Robert Braun I want to reduce and analyse WSRT HI synthesis observations of the high-velocity gas in the vicinity of M31 which was found by Thilker et al. with the GBT. The WSRT data reveal several compact clumps in these gas structures which were barely resolved with the 9' beam of the GBT. We expect that the detailed WSRT observations will provide additional clues on the nature and origin of the high-velocity gas around M31.
