We set out to reconstruct their formation histories, and to probe their structure and evolution. In this regard, we have conducted an optical long-term monitoring survey of the majority of dwarf galaxies in the LG, with the Isaac Newton Telescope (INT), to identify the most evolved AGB stars that are long period variable (LPV). The LPV stars reach the largest amplitudes of their brightness variations at optical wavelengths, due to the changing temperature. They trace stellar populations as young as 30 Myr to as old as 10 Gyr and identifying th ... 14:00 - 16:00 Seminar Coherent neural oscillations between cortical areas define the dynamics of working memory and its interaction with selective attention School COGNITIVE SCIENCES Venue: School of Cognitive Sciences, Institute for Research in Fundamental Sciences (IPM), Opposite the ARAJ, Artesh Highway, Tehran, Iran on map * To join the mailing list: Send an empty email to: scs at ipm dot ir on the subject of: #join ... 14:00 - 15:00 Weekly Seminar Condensed Matter and Statistical Physics Group Many-body perturbation theory study of doped TiO2 School PHYSICS Seminar Room (classroom A), Farmanieh Building, IPM ... 14:00 - 15:00 Weekly Seminar Combinatorics and Computing Weak saturation in random graphs School MATHEMATICS Weak saturation in random graphs ... 14:00 - 15:00 Weekly Seminar Many-body perturbation theory study of doped TiO2 School NANO SCIENCES Many-body perturbation theory study of doped TiO2 Abstract: Doping is one of the most common strategies for improving the photocatalytic and solar energy conversion properties of TiO2, hence an accurate theoretical description of the electronic and optical properties of doped TiO2 is of both scientific and practical interest. In this talk I will present the electronic structure, optical absorption spectra and excitonic properties of H- and Nb- doped TiO2 calculated by ab initio calculations based on density functional theory, GW approximation and Bethe-Salpeter equation. Our results show defect energ ... 15:00 - 16:00 Weekly Seminar A three-dimensional map of the hot Local Bubble using diffuse interstellar bands School PARTICLES AND ACCELERATORS Abstract: The Solar System is located within a low-density cavity, known as the Local Bubble, which appears to be filled with an X-ray emitting gas at a temperature of 10^6 K. Such conditions are too harsh for typical interstellar atoms and molecules to survive. There exists an enigmatic tracer of interstellar gas, known as Diffuse Interstellar Bands (DIB), which often appears as absorption features in stellar spectra. The carriers of these bands remain largely unidentified. Here we report the three-dimensional structure of the Local Bubble using two different DIB tracers (5780A and 5797A), which reveals that DIB carriers are present within t ... |
