Next IAS meeting!
“Is the Hubble constant a true constant? 100 years of an expanding Universe.”
Talk Details
This year marks the 100th anniversary of Lundmark’s paper providing strong observable evidence of the expansion of the Universe. Together with the theoretical evidence provided by Friedmann in 1922, these observations can be considered the birth of cosmology as we now know it. Many efforts have been made to study and measure such expansion.
From Hubble’s observations, confirming Lundmark’s results, to the use of type Ia supernova and more recently the use of the microwave background radiation observed by the Planck space mission. The result is several Nobel Laureates and two possible values that don’t seem to agree with each other. In this talk, I will talk about the most recent measurements of the Hubble constant (and why we care about them), their limitations and how the next decade (or two) could see another Nobel winner in Physics in this field; maybe destroying most of our current extragalactic calculations and why not opening the door to new exciting discoveries.
Biography
Prof. Antonio Martin-Carrillo
Antonio Martin-Carrillo is an UCD Ad Astra fellow/Assistant Professor in the School of Physics. He graduated with a BSc and MSc in Physics with Astronomy from University Complutense Madrid. Following 2 years working at the European Space Agency as part of the XMM-Newton space observatory calibration team, he moved to UCD where he completed his PhD investigating gamma-ray bursts (GRBs) and pulsars. He is currently a member of the Space Science Group studying the transient Universe and in particular the prompt and afterglow emission of GRBs using high-energy space observatories and ground-based telescopes such as UCD’s Watcher robotic telescope.
His research also includes the development of software tools for advanced data analysis. As such he is an ambassador and collaborator on the Astropy project aimed at providing a wide range of software packages written in Python for use in astronomy. He is also a member of the INTEGRAL multi-messenger group searching for gamma-ray counterparts to gravitational waves, neutrino events and other transient sources; the ATHENA X-ray space observatory, an ESA large mission scheduled to launch in 2028, and the THESEUS space telescope, currently in its study phase with ESA.
