  1. To Survive or To Shatter: The Impact of Cosmic Rays on the Fate of Stripped Cold Clouds

    Publication
    Does cosmic ray (CR) pressure matter for the circumgalactic medium (CGM)? Despite growing interest, this remains a debated question, complicated by limited observational constraints and differing implementations of …

  2. Great Balls of Fire: Star Formation in Gas Clouds Accelerated by a Hot Wind

    Publication
    Satellite galaxies undergo ram pressure stripping, in which their gas is directly removed by a hydrodynamical interaction with the surrounding host halo gas. In clusters, ram pressure stripped …

  3. Exploring the Impact of Active Galactic Nucleus Feedback Model Variations on the Ly\(\alpha\) Forest Flux Power Spectrum

    Publication
    We study the effects of varying different Active Galactic Nuclei (AGN) feedback parameters on the Lyman-\(\alpha\) (Ly\(\alpha\)) forest 1D transmitted flux power spectrum (P1D). We use …

  4. Mechanisms Affecting Galaxies Nearby and Environmental Trends (MAGNET)

    Publication
    [ABRIDGED] Galaxy evolution is shaped by internal and external mechanisms that regulate the baryon cycle and star formation activity. We present a theoretical framework based on the …

  5. The supersonic nature of jellyfish galaxies

    Publication
    All gas-rich galaxies in cluster environments are expected to experience ram-pressure stripping from the intra-cluster medium. However, only a fraction of these develop ongoing star …

  6. Distinguishing ram pressure from gravitational interactions: Applying the size-shape difference method to real galaxies

    Publication
    In dense environments, mechanisms like ram pressure stripping (RPS) and gravitational interactions can induce similar morphological features in galaxies, distinguishable only through detailed study of their stellar properties …

  7. Distinguishing ram pressure from tidal interactions: Size-shape difference measure

    Publication
    Aims. In dense environments, disk galaxies can be subjected to tidal interactions with other galaxies and/or ram pressure stripping. Some morphological features are clearly associated with one …

  8. The MUSE view of ram pressure stripped galaxies in clusters: The GASP sample

    Publication
    We present the full sample of 76 galaxies in 39 galaxy cluster fields at z = 0.04 to 0.07 observed with VLT/MUSE by the GAs Stripping …

  9. Searching for Correlations between Satellite Galaxy Populations and the Cold Circumgalactic Medium around TNG50 Galaxies

    Publication
    We investigate the impact of satellites, a potentially important contributor toward the cold gas assembly of a halo, on the cold gas budgets of 197 TNG50 simulated halos …

  10. What goes around comes around: The fate of stars in stripped tails of gas

    Publication
    We conducted high-resolution wind-tunnel simulations to study in situ star formation in the stripped tails of two massive (M\(_{\rm star}\) = 10\(^{11}\) M\(_{\odot}\)) galaxies …

  11. The Effects of Active Galactic Nuclei Feedback on the Ly\(\alpha\) Forest Flux Power Spectrum

    Publication
    We study the effects of active galactic nuclei (AGN) feedback on the Ly\(\alpha\) forest 1D flux power spectrum (P1D). Using the SIMBA cosmological-hydrodynamic simulations, we examine …

  12. BreakBRD Galaxies: Evolutionary Clues through an Analysis of Gas Content

    Publication
    By combining newly obtained deep Green Bank Telescope 21 cm observations with optical spectroscopic data, we present an analysis of the gas content of break bulges in red …

  13. Observational Predictions for the Survival of Atomic Hydrogen in Simulated Fornax-like Galaxy Clusters

    Publication
    The presence of dense, neutral hydrogen clouds in the hot, diffuse intra-group and intra-cluster medium is an important clue to the physical processes controlling the survival …

  14. When and How Ram Pressure Stripping in Low-mass Satellite Galaxies Enhances Star Formation

    Publication
    We investigate how a satellite's star formation rate (SFR) and surviving gas respond to ram pressure stripping (RPS) in various environments. Using a suite of high-resolution …

  15. The surprising lack of effect from stellar feedback on the gas stripping rate from massive jellyfish galaxies

    Publication
    We study the role of star formation and stellar feedback in a galaxy being ram pressure (RP) stripped on its infall into a cluster. We use hydrodynamical wind …

  16. Seeding the CGM: how satellites populate the cold phase of milky way haloes

    Publication
    The origin of the cold phase in the circumgalactic medium (CGM) is a highly debated question. We investigate the contribution of satellite galaxies to the cold gas budget …

  17. An Improved and Physically Motivated Scheme for Matching Galaxies with Dark Matter Halos

    Publication
    The simplest scheme for predicting real galaxy properties after performing a dark matter simulation is to rank order the real systems by stellar mass and the simulated systems …
