Description
The first results on new optical data for R Aquarii (based on observations obtained with the 2.5m INT, the 2.5m NOT and the 3.5m NTT) are presented. The morphology and kinematics of the nebula, based on data obtained with the NTT from 1991 to 2000, are discussed. Physical parameters of the outer nebula and the knotty jet are derived using spectra obtained with the INT in 2001. From the analysis of all these data we propose that the spectacular knotty inner structure of R Aqr could result from the interaction of a highly collimated pulsating young jet with the older hourglass inner nebula.

    The Undiscovered Ultra Diffuse galaxies of the Local Group: predictions from constrained cosmological simulations
    Ultra-diffuse galaxies (UDGs) are attractive candidates to probe cosmological models and test theories of galaxy formation at low masses; however, they are difficult to detect because of their low surface brightness. In the Local Group a handful of UDGs have been found to date, most of which are satellites of the Milky Way and M31, and only two are

    Deriving Star Formation Histories of Galaxies from Spectra with Simulation-based Inference
    High-resolution galaxy spectra 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, in particular, the triggers

    A Combined Analysis of Jeans Kinematics and Milli-Second Pulsar Timing Effects: Probing the Mass Contents of Omega Centauri
    We explore the interplay between Jeans analyses of velocity dispersions and millisecond-pulsar (MSP) timing measurements that trace line-of-sight accelerations to analyze the kinematics of Omega Centauri, performing the first combined analysis of its kind. By using HST proper motion data and recent MSP kinematic measurements, we are able to tightly
