11:00 - 13:00 Weekly Seminar Exploring Stellar Populations School ASTRONOMY Abstract Understanding the luminosity of unresolved stellar populations is recognized as a crucial aspect of galaxy evolution studies. This presentation will address how detailed information from resolved stellar populations is leveraged to infer the physical properties of unresolved populations through stellar population synthesis (SPS) models. A key focus will be placed on the role of the initial mass function (IMF) and the impact of dust in shaping the observed luminosity. By bridging theoretical frameworks with observational data, models can be refined to enhance the interpretation of the luminosity of distant, unresolved populatio ... 14:00 - 15:00 Weekly Seminar HEPCo Group Stochastic Gravitational Wave Background in the present and future planned experiments School PHYSICS Date and time Tuesday, October 29th, 2024 (Aban 8th, 1403), 2:00 pm (Tehran zone) Link https://www.skyroom.online/ch/schoolofphysics/highenergyseminar Abstract I will talk about a particular class of inflation, named hybrid inflation. I will describe the formation of one of the topological defects, Cosmic Strings, after inflation as a result of phase transition to be a promising phenomenon for probing the unseen universe via a Stochastic Gravitational Wave Background. Cosmic Strings may have an imprint on the Cosmic Microwave Ba ... |
