DESI Observations of the Andromeda Galaxy: Revealing the Immigration History of Our Nearest Neighbor
The Astrophysical Journal, 2023 We present Dark Energy Spectroscopic Instrument (DESI) observations of the inner halo of M31, which reveal the kinematics of a recent merger—a galactic immigration event—in exquisite detail.

Discovery of 20 UV-emitting SNRs in M31 with UVIT
The Astronomical Journal, 2023 We present the first catalog of supernova remnants (SNRs) in M31 that exhibit diffuse ultraviolet (UV) emission. UV images of M31 were obtained by the Ultraviolet Imaging Telescope (UVIT) on the AstroSat satellite, and the list of SNRs was obtained from ...

Xanthomonas euvesicatoria Associated With Outbreaks of Bacterial Blight of Onion in Central Brazil
Plant Pathology, Volume 75, Issue 4, July‐August 2026.An investigation into bacterial blight (Xanthomonas euvesicatoria) outbreaks in Brazilian onions highlights the critical role of weeds and leftover soybeans as pathogen reservoirs. Effective disease control requires managing these alternative hosts. ABSTRACT Since 2018, outbreaks of typical bacterial blight caused by Xanthomonas have been observed in ...

European Journal of Philosophy, Volume 34, Issue 2, Page 423-440, June 2026.ABSTRACT Making sense of the world often requires one to come up with new ideas, including ideas one had previously been unable to think of. How and when should this be done? I propose and defend a norm of rationality linking wondering, belief, and abilities to conceive: one must not both wonder a question and reject all answers to it that one can ...

Global Change Biology, Volume 32, Issue 6, June 2026.Rewetting drained boreal peatland forests is increasingly promoted as a climate mitigation strategy, yet its effects on carbon (C) and greenhouse gas (GHG) balances remain uncertain. This study quantified CO2 and CH4 fluxes over 2 years before and after rewetting in a low‐productive peatland forest, with and without tree harvest.
