    Exploring the most extreme gamma-ray blazars using broadband spectral energy distributions
    Context. Extreme high-synchrotron peaked blazars (EHSPs) are rare high-energy sources characterised by synchrotron peaks beyond 10 17 Hz in their spectral...

    Exploring the nature of dark matter with the extreme galaxy AGC 114905
    AGC 114905 is a dwarf gas-rich ultra-diffuse galaxy seemingly in tension with the cold dark matter (CDM) model. Specifically, the galaxy appears to have an...
  • Publication
    Exploring the stellar populations of backsplash galaxies
    Backsplash galaxies are those that traverse and overshoot cluster cores as they fall into these structures. They are affected by environment, and should stand...

    Exploring the Very Extended Low-surface-brightness Stellar Populations of the Large Magellanic Cloud with SMASH
    We present the detection of very extended stellar populations around the Large Magellanic Cloud (LMC) out to R ∼ 21°, or ∼18.5 kpc at the LMC distance of 50 kpc...

    Extended Broad Balmer Emission in the Seyfert 1 Galaxy Markarian 509
    We present two-dimensional spectroscopic observations of the circumnuclear region of Mrk 509. The spectra show extended (off-nuclear) broad Balmer emission (...

    Extended Hα over compact far-infrared continuum in dusty submillimeter galaxies. Insights into dust distributions and star-formation rates at z ∼ 2
    By using data from the Atacama Large Millimeter/submillimeter Array and near-infrared (NIR) integral field spectrographs, including both Spectrograph for...

    Extended soft X-ray emission in 3CR radio galaxies at z < 0.3: high excitation and broad line galaxies
    We analyze Chandra observations of diffuse soft X-ray emission associated with a complete sample of 3CR radio galaxies at z 0.3. We focus on the properties of...
  • Publication
    Extended warm gas in the ULIRG Mrk273: Galactic outflows and tidal debris
    We present new HST/ACS medium- and narrow-band images and optical Isaac Newton Telescope long-slit spectra of the merging system Mrk273. The HST observations...
  • Publication
    Extended X-ray emission associated with the northern hotspot of 3C 390.3
    ROSAT Position Sensitive Proportional Counter (PSPC) observations of the double-lobed radio source 3C 390.3 show resolved X-ray emission spatially located at...
