Descripción
We report on the follow up observations after the report of ~10 mHz quasi-periodic oscillations (QPO -- ATel #3225) in the X-ray light curve of the ongoing outburst of the black hole candidate IGR J17091-3624 (ATel #3144, #3159, #3167, #3203) RXTE/PCA observations performed on March 19th and March 22nd, 2011, show a continuous progression of flare-like events which occur very regularly in a quasi-periodic manner at a rate between 25 and 30 mHz.

    Inferring stellar population properties from HST+JWST photometry using Normalizing Flows
    Spectral energy distributions (SEDs) encode information about the stellar populations within galaxies. By investigating the properties of these stars, such as their ages, masses, and metallicities, we can gain insights into the underlying physical processes that drive the growth and transformation of galaxies over cosmic time. For this purpose, we

    The importance of professional role models and changing stereotypes in fostering STEM vocations
    Recent studies show that in Europe we are losing women's talent in some key disciplines for the future, particularly those directly related to astronomy. In order to get more girls and young women interested in the so-called STEM (Science, Technology, Engineering and Mathematics) fields, it is necessary to change the highly entrenched stereotypes

    Mass and radius determination of young planets and the implications for their gas envelope evolution
    Despite thousands of extrasolar planets discovered to date, the dominant mechanisms forming planets and the timescales of planetary migration and atmospheric evaporation remain to be probed observationally. To shed light on these mechanisms, we performed a combined photometric and spectroscopic analysis of several young transiting systems at
