Time Series Analysis Applied to Geomagnetic Indices Abstract: Geomagnetic indices, based on magnetic field observations at the Earth’s surface, provide almost continuous monitoring of Earth’s magnetospheric and ionospheric activity. AE and DST are two such indices designed to measure… Read More

Invisible Monsters and Spider Webs: Compact objects in the era of wide field optical surveys Abstract: Where are the missing Galactic population of black holes? How do we obtain precise and accurate masses for black holes and neutron stars… Read More

Colliding Wind Binary Systems and their Thermal and Non-Thermal Radiation Abstract: Colliding Wind Binary (CWB) systems consist of two massive (O or WR type) stars whose winds collide. The high velocity winds are thermalized in this collision zone and… Read More

Studying the Magnetospheric Plasmas of Mercury and Earth using ULF Waves and Machine Learning Abstract: Ultra low frequency (ULF) waves are a key mechanism for the transmission of energy and information around planetary magnetospheres and whose unique characteristics… Read More

A Hidden Brown Dwarf? The MUSE view of a precessing stellar jet Abstract: Protostellar jets are a dramatic and ubiquitous phenomenon of young accreting stars which can shed light on many aspects of the star and protoplanetary disk formation…. Read More

VVV Microlensing events around the Galactic Center Abstract: We discovered ~1,000 microlensing events within an area covering 20.68 deg^2 between 2010 and 2015 in the zero-latitude region of the Galactic bulge using the VVV Survey near-IR data. We used… Read More
