    On the Collisional Disalignment of Dust Grains in Illuminated and Shaded Regions of IC 63
    Interstellar dust grain alignment causes polarization from UV to mm wavelengths, allowing the study of the geometry and strength of the magnetic field. Over the...

    On the Dearth of Ultra-faint Extremely Metal-poor Galaxies
    Local extremely metal-poor galaxies (XMPs) are of particular astrophysical interest since they allow us to look into physical processes characteristic of the...

    On the Diagnostic Potential of Hα for Chromospheric Magnetism
    We investigate the feasibility of measuring line-of-sight magnetic field strength in the solar chromosphere through Stokes polarimetry in the hydrogen Hα line...

    On the Effects of the Evolution of Microbial Mats and Land Plants on the Earth as a Planet. Photometric and Spectroscopic Light Curves of Paleo-Earths
    Understanding the spectral and photometric variability of the Earth and the rest of the solar system planets has become of utmost importance for the future...
  • Publication
    On the Environmental Dependence of the Cluster Galaxy Assembly Timescale
    We present estimates of CN and Mg overabundances with respect to Fe for early-type galaxies in eight clusters over a range of richness and morphology. Spectra...
