SUMMARY:The Index Diagram as a Tool to Disentangle Host Galaxy Contributions in Quasar Spectra
DESCRIPTION:We revisit the Quasar Main Sequence (QMS) by investigating the impact of the stellar component from the host galaxy (HG) on the emission-line spectra of active galactic nuclei (AGN). After identifying SDSS-DR19 spectra with broad emission lines\, we constructed the Index diagram\, a novel\, model-independent diagnostic based on redshift-corrected spectra\, designed to efficiently identify sources with significant stellar HG contributions and to classify AGN spectra into three categories: HG-dominated (HGD)\, intermediate (INT)\, and AGN-dominated (AGND) sources. \nOur QMS analysis shows that HGD sources predominantly occupy the Population B region\, typically exhibiting negligible Fe II emission\, while INT and AGND sources display similar distributions in the Population A region. Cross-matching with radio\, infrared\, and X-ray catalogues reveals that the strongest radio emitters are preferentially associated with HGD and INT sources\, whereas strong X-ray emitters are found among INT and AGND objects\, which also populate the AGN region in the WISE colour diagram. The applicability of the Index diagram is also demonstrated by its implementation in large spectroscopic datasets\, including SDSS DR20 and DESI\, enabling systematic studies of AGN-HG decomposition across big data samples. \nFecha y lugar: 09/06/2026 – 12:30 | Salón de ActosAlenka NegreteInstituto de Astronomía – UNAM \n  \n

SUMMARY:Venus as an Anchor Point for Planetary Habitability
DESCRIPTION:A fundamental aspect of understanding the limits of habitable environments and detectable signatures is the study of where the boundaries of such environments can occur\, and the conditions under which a planet is rendered into a hostile environment. In our solar system\, Venus is the most Earth-like planet\, yet at some point in planetary history there was a bifurcation between the two: Earth has been continually habitable since the end-Hadean\, whereas Venus became uninhabitable. Indeed\, Venus is the type-planet for a world that has transitioned from habitable and Earth-like conditions\, through the inner edge of the Habitable Zone (HZ); thus it provides a natural laboratory to study the evolution of habitability. \nIn this talk I will describe the gaps in our knowledge regarding Venus within the context of how these gaps are impacting our ability to model exoplanet atmospheres and interiors. I will discuss various factors that relate to a possible habitable past of Venus\, including orbital evolution. I will outline exoplanet target selection for testing the conditions of runaway greenhouse and present examples of potential Venus analogs. \nFinally\, I will summarize the primary exoplanet science questions that will be addressed by the coming NASA and ESA missions to Venus. \n  \nFecha y lugar: 22/10/2026 – 12:30 | Salón de ActosStephen KaneUniversity of California\, Riverside \n
