“Searching for Pulsars with Effelsberg” Pulsars are fundamental tools for astronomy and physics. Every single new pulsar has the potential to provide an outstanding laboratory for a wide variety of physics, ranging from a better understanding of the stellar evolution to testing theories of gravity and placing limits on the equation-of-state. Although more than 2500 pulsars […]

Observations of star forming regions at (sub)millimetre and centimetre wavelengths have allowed astronomers to detect numerous molecules including some of the most complex molecules ever observed in the interstellar medium. One of the best targets to study these complex organic molecules (COMs) is the Sagittarius B2 (Sgr B2) molecular cloud, located in the central molecular zone, […]

Speaker: Vishnu Balakrishnan Title: “New Techniques to search for Relativistic Binary Pulsars.” Abstract: Pulsars, rapidly-rotating highly-magnetised neutron stars, are fantastic natural laboratories and allow for a wide range of fundamental scientific applications. To date, over 2600 pulsars have been found, and the search to find more is constantly ongoing. Since the discovery of the first binary […]

Speaker: Madhuri Gaikwad Title:”Pulsar timing studies with EPTA and LEAP” Abstract pulsars are very interesting objects and can be used as tools to study various physics. One such system is PSR J1012+5307. This system helps constrain many parameters required to study the alternative theory of gravity. We use five major telescopes to study these effects.. Also […]

Title: J2222-0137’s potential to verify dipolar gravitational waves Alongside the theory of general relativity (GR) Scalar-Tensor theories (STT) of gravitation are important contenders for describing gravitational interaction between bodies. These theories predicting deviations from GR can be tested in the solar system environment and by timing radio pulsars. In my talk I describe the pulsar-white dwarf […]

Title: Internal Structure of Massive Star-forming Clumps Abstract: Previous observations have revealed that massive dense clumps are the main locations where OB star-formation is taking place. Understanding massive clump evolution will yield critical constraints for constructing a massive star-formation scenario. In this talk, I will present the statistical study of clump-scale fragmentation based on submillimeter continuum […]

Compact galaxy clusters are ideal laboratories for studying intense evolutionary activity. Stephan’s Quintet, a compact galaxy cluster consisting of 5 galaxies, is the home to extensive inter-galactic star formation, active nuclei, previous interactions that can be traced via tidal tails as well as a current shock-inducing interaction. Through studying the gas and stellar dynamics of such […]

……………………………………………………………….1st (Chair: Marilyn Cruces)………………………………………………………………. Speaker: Felix Pötzl Title: “Magnetic fields in AGN jets” Abstract: Supermassive black holes (SMBHs) in the centres of radio-loud active galactic nuclei (AGN) produce collimated relativistic outflows (jets). Very Long Baseline Interferometry (VLBI) observations are needed to study the spatial origin and launching mechanism of those jets, where magnetic fields are thought […]

Speaker: Enrico Garaldi Title: The radial acceleration relation in ΛCDM satellites ABSTRACT: The radial acceleration measured in bright galaxies tightly correlates with that generated by the observed distribution of baryons, a phenomenon known as the radial acceleration relation (RAR). Dwarf spheroidal satellite galaxies have been recently found to depart from the extrapolation of the RAR measured […]
