JWST observes the assembly of a massive galaxy at $z\sim4$
The Open Journal of AstrophysicsWe present JWST observations of the radio galaxy TGSSJ1530+1049, spectroscopically confirmed at $z=4.0$. NIRCam images and NIRSpec/IFU spectroscopy ($R=2700$) show that TGSSJ1530+1049 is part of one of the densest-known structures of continuum and line ...

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Detection of radio continuum emission from Procyon
The Astrophysical Journal, 1993 We have detected the F5 IV-V star Procyon as a weak and variable 3.6 cm radio continuum source using the VLA. The inferred radio luminosity is similar to, though some-what higher than, the X-band luminosity of the active and flaring sun. The 33 micro-Jy flux density level at which we detected Procyon on four of five occasions is close to the 36 micro ...

The influence of the cluster environment on the large-scale radio continuum emission of 8 Virgo cluster spirals [PDF]
, 2010 The influence of the environment on the polarized and total power radio continuum emission of cluster spiral galaxies is investigated. We present deep scaled array VLA 20 and 6 cm observations including polarization of 8 Virgo spiral galaxies. These data

Aspect dependent optical continuum emission in radio quasars
, 1996 We have defined a new, complete, low-frequency selected sample of southern radio quasars, the Molonglo Quasar Sample, with the aim of studying the aspect dependence of the radio and optical emission. As a test for enhancement of the optical continuum, we
