Sangeeth Kochanthara won one of the Best PhD Thesis Awards by the Dutch National Association for Software Engineering !🎓🏆

Sangeeth Kochanthara, from COMPAS group, a systems engineer at SDC, won one of the Dutch National Association for Software Engineering PhD awards. Dutch National Association for Software Engineering (VERSEN - VEReniging Software Engineering Nederland) is a National Association for Software Engineering supported by NWO. Every year, VERSEN awards the best three Ph.D. theses in software engineering based on novelty, impact, timeliness, quality of the thesis and associated artifacts, methodological approach, and execution. The award ceremony took place on the 11th of April at NWO ICT.OPEN at the Beatrix Theater, Jaarbeurs Utrecht.

Sangeeth defended his Ph.D. in Computer Science Engineering at Eindhoven University of Technology. His thesis, ‘A Changing Landscape: On Safety & Open Source in Automated and Connected Driving’ explored the safety of traditional and machine learning software for next-generation connected and autonomous driving vehicles. The thesis' main contributions include identifying safety issues in the design of the software of the next-generation automotive systems, proposing a method to ensure safety that complies with safety standards, and exploring the adoption of open source by the automotive industry.

The Commensal Radio Astronomy FAST Survey (CRAFTS)

The Five-hundred-meter Aperture Spherical radio Telescope (FAST) has released its first call for proposal and will be open to the international community next year. Based on a novel technique of high-cadence CAL injection, we have realized the world's first calibrated commensal survey mode, simultaneously taking data for pulsar search, HI galaxies, HI imaging, and FRBs. I introduce here one of the major survey plans, namely, the Commensal Radio Astronomy FAST Survey (CRAFTS, Li et al. 2018), which has discovered more than 100 new pulsars, including a few dozen MSPs, 5 new FRBs, including one new repeater. I will also briefly describe recent FAST results from CRAFTS and other dedicated programs, including new insights into the characteristic energy of FRBs, the formation process of neutron stars, the evolution of interstellar medium, etc.

Extreme UV Emission: Bridging Galaxy Evolution Across Cosmic Time

In the last few years, our first glimpse of the spectral properties of z∼5−7 galaxies has emerged. Deep UV spectra have revealed prominent high-ionization nebular emission lines (i.e., C IV, He II, C III]) indicating that extreme radiation fields may be characteristic of reionization-era systems. While such strong high-ionization emission lines are atypical of the well-studied z∼0−3 galaxy samples, our recent UV spectral campaigns have revealed several galaxies with analogous emission-line features to reionization-era systems. I will discuss the recent detection of extremely strong UV emission in nearby galaxies and the potential sources of their very hard ionizing radiation fields. Such strong detections of high-ionization emission lines have been linked to the leakage of Lyman continuum (LyC) photons (necessary for reionization) both theoretically and observationally. These extreme UV emission-line dwarf galaxies provide a template for the extreme conditions that are important for reionization, however their features are still poorly understood. In preparation for the coming UV window onto the early universe with the advent of ELTs and JWST, I will introduce the COS Legacy Archival Spectroscopic SurveY - an upcoming large HST program designed to disentangle the stellar and nebular spectral signatures of 45 star-forming galaxies. This program will calibrate new UV diagnostics that will allow us to trace galaxy evolution to the distant universe, unveiling the properties of reionization-era galaxies.
