High-cadence Timing of Binary Pulsars with CHIME
We performed near-daily observations on the binary pulsars PSR J0218+4232, PSR J1518+4904 and PSR J2023+2853 with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). For the first time, we detected the Shapiro time delay in all three pulsar-binary systems, using only 2--4 years of CHIME/Pulsar timing data. We measured the pulsar masses to be $1.49^{+0.23}_{-0.20}$ M$_\odot$, $1.470^{+0.030}_{-0.034}$ M$_\odot$ and $1.50^{+0.49}_{-0.38}$ M$_\odot$ respectively. The companion mass to PSR …

"Software engineers are not always aware that our cherished Silicon Valley was a side effect (with apologies to our readers fond of functional programming) of the San Francisco counterculture of the late 60s. Such a movement and its devotion to LSD gave us Scott McKenzie singing at the Monterey Festival (where a certain Ravi Shankar made his debut in front of an American audience), and it also sparked influential software companies with names like Lotus, Sun, and Apple."

Geoffrey James
Western culture has long been fascinated with what the French call "Extrême-Orient"; since the times of Marco Polo, most probably since biblical times. We (the editors of a magazine that is, after all, a pure product of Western civilization) assign certain qualities to the thinking patterns of those regions: wisdom, calmness, thoughtfulness, and reflection. Eastern philosophy is often analyzed in counterpoint, in a tangential or even orthogonal fashion from its western counterpart: Confucius v…

An Excess of AGNs Triggered by Galaxy Mergers in MaNGA Galaxies of Stellar Mass $\sim10^{11}$ $M_{\odot}$
To facilitate new studies of galaxy merger driven fueling of active galactic nuclei (AGNs), we present a catalog of 387 AGNs that we have identified in the final population of over $10,000$ $z<0.15$ galaxies observed by the SDSS-IV integral field spectroscopy survey Mapping Nearby Galaxies at Apache Point Observatory (MaNGA). We selected the AGNs via mid-infrared WISE colors, Swift/BAT ultra hard X-ray detections, NVSS and FIRST radio observations, and broad emission lines in SDSS spectra. By c…

Hydrogen plasma inhibits ion beam restructuring of materials
Focused ion beam (FIB) techniques are employed widely for nanofabrication, and processing of materials and devices. However, ion irradiation often gives rise to severe damage due to atomic displacements that cause defect formation, migration and clustering within the ion-solid interaction volume. The resulting restructuring degrades the functionality of materials, and limits the utility FIB ablation and nanofabrication techniques. Here we show that such restructuring can be inhibited by perform…
