<jats:title>Abstract</jats:title> <jats:p>We examine Parker Solar Probe (PSP) magnetic field and plasma observations during its first encounter with the Sun in early 2018 November. During this perihelion time, impulsive reversals in the magnetic field, called “switchbacks,” were found in the data set characterized by a quick rotation in <jats:italic>B</jats:italic> along with a simultaneous increase in solar wind flow. In this work, we examine the structure and morphology of 920 switchback boundaries as PSP enters and exits the structures, specifically looking for evidence of boundary degradation, dissipation, and associated ultralow frequency (ULF) magnetic wave activity. We find that boundaries with the most abrupt, step-function-like change in <jats:italic>B</jats:italic> <jats:sub>r</jats:sub> and <jats:italic>V</jats:italic> <jats:sub>r</jats:sub> also show little evidence of dissipation and ULF wave activity. In contrast, there is a set of boundaries that appears highly degraded with ULF magnetic activity in the vicinity of the boundary. We thus infer that the steep, step-like boundaries with little ULF activity are relatively young in comparison to the degraded boundaries. The distribution in relative ages suggests that the switchback boundary formation process is dynamic and evolving, even occurring near the PSP observation point inside of 40 <jats:italic>R</jats:italic> <jats:sub> <jats:italic>s</jats:italic> </jats:sub>.</jats:p>

<jats:title>Abstract</jats:title> <jats:p>This study uses H <jats:sc>i</jats:sc> image data from the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) pilot survey with the Australian Square Kilometre Array Pathfinder (ASKAP) telescope, covering the Hydra cluster out to 2.5<jats:italic>r</jats:italic> <jats:sub>200</jats:sub>. We present the projected phase–space distribution of H <jats:sc>i</jats:sc>-detected galaxies in Hydra, and identify that nearly two-thirds of the galaxies within <jats:inline-formula> <jats:tex-math> <?CDATA $1.25{r}_{200}$?> </jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mn>1.25</mml:mn> <mml:msub> <mml:mrow> <mml:mi>r</mml:mi> </mml:mrow> <mml:mrow> <mml:mn>200</mml:mn> </mml:mrow> </mml:msub> </mml:math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="apjabfc52ieqn1.gif" xlink:type="simple" /> </jats:inline-formula> may be in the early stages of ram pressure stripping. More than half of these may be only weakly stripped, with the ratio of strippable H <jats:sc>i</jats:sc> (i.e., where the galactic restoring force is lower than the ram pressure in the disk) mass fraction (over total H <jats:sc>i</jats:sc> mass) distributed uniformly below 90%. Consequently, the H <jats:sc>i</jats:sc> mass is expected to decrease by only a few 0.1 dex after the currently strippable portion of H <jats:sc>i</jats:sc> in these systems has been stripped. A more detailed look at the subset of galaxies that are spatially resolved by WALLABY observations shows that, while it typically takes less than 200 Myr for ram pressure stripping to remove the currently strippable portion of H <jats:sc>i</jats:sc>, it may take more than 600 Myr to significantly change the total H <jats:sc>i</jats:sc> mass. Our results provide new clues to understanding the different rates of H <jats:sc>i</jats:sc> depletion and star formation quenching in cluster galaxies.</jats:p>
