Abstract Isolated geomagnetic storms during solar minimum offer the opportunity to observe effects of wind on Earth's atmosphere without interference from other background changes in ionosphere‐thermosphere system. Here, we a minor storm ionosphere at middle and low latitudes, where disturbances thermospheric winds composition can produce storm‐time ionospheric densities. Using data NASA Ionospheric Connection Explorer (ICON), investigate competing neutral modifying 25 January 2021 storm....
We present BVRI and unfiltered Clear light curves of 70 stripped-envelope supernovae (SESNe), observed between 2003 2020, from the Lick Observatory Supernova Search (LOSS) follow-up program. Our SESN sample consists 19 spectroscopically normal SNe~Ib, two peculiar SNe Ib, six SN Ibn, 14 Ic, one ten Ic-BL, 15 IIb, ambiguous IIb/Ib/c, superluminous SNe. photometry has (on a per-SN basis) mean coverage 81 photometric points (median 58 points) cadence 3.6d 1.2d). From our full sample, subset 38...
The DARWIN collaboration recently argued that (dark matter wimp search with liquid xenon) can collect, via neutrino-electron scattering, a large, useful sample of solar $pp$-neutrinos, and measure their survival probability subpercent precision. We explore the physics potential such in more detail. estimate that, 300 ton-years data, also measure, help current neutrino value ${\mathrm{sin}}^{2}{\ensuremath{\theta}}_{13}$, to exclude ${\mathrm{sin}}^{2}{\ensuremath{\theta}}_{13}=0$ close...
A string of recent studies has debated the exact form and physical origin an evolutionary trend between peak luminosity Type Ia supernovae (SNe Ia) properties galaxies that host them. We shed new light on discussion by presenting analysis ~200 low-redshift SNe in which we measure separation Hubble residuals (HR; as probes luminosity) two host-galaxy morphological types. show this can test predictions made recently proposed models, using independently empirically determined distribution each...
The DARWIN collaboration recently argued that (DARk matter WImp search with liquid xenoN) can collect, via neutrino--electron scattering, a large, useful sample of solar $pp$-neutrinos, and measure their survival probability sub-percent precision. We explore the physics potential such in more detail. estimate that, 300 ton-years data, also measure, help current neutrino value $\sin^2θ_{13}$, to exclude $\sin^2θ_{13}=0$ close three-sigma level. some detail how well constrain existence new...
