With a focus on off-the-shelf components, Twinkle is the first in series of cost competitive small satellites managed and financed by Blue Skies Space Ltd. The satellite based high-heritage Airbus platform that will carry 0.45 m telescope spectrometer which provide simultaneous wavelength coverage from 0.5-4.5 $\rm{μm}$. spacecraft prime Stevenage while being developed Toulouse ABB Canada. Scheduled to begin scientific operations 2025, sit thermally-stable, sun-synchronous, low-Earth orbit....

The Twinkle telescope is a space-based observatory conceived to study solar system objects, exoplanets, brown dwarfs, protoplanetary disks and stars. satellite based on high-heritage platform will carry visible infrared spectrograph providing simultaneous broad wavelength coverage. Launching into Sun-synchronous low-Earth polar orbit, operate from highly stable thermal environment for baseline lifetime of seven years.In this presentation, the team provide latest updates mission highlight...

Mauve is a satellite equipped with 13-cm telescope and UV-Visible spectrometer (with anoperative wavelength range of 200-700 nm) conceived to measure stellar magnetic activity andvariability. The science program will be delivered via multi-year collaborative survey program,with thousands hours each year available for long baseline observations hundreds stars,unlocking significant time domain astronomy opportunity. Mauve’s mission lifetime 3 yearswith the ambition 5 years, cover...

We examine the physical conditions, environments, and statistical properties of intergalactic Ovi, Ovii Oviii absorbers in Simba cosmological hydrodynamic simulation suite. The goal is to understand nature these high ionisation absorbers, test Simba's surprising prediction that $\sim 70\%$ cosmic baryons at $z=0$ are Warm-Hot Intergalactic Medium (WHIM) driven by jet feedback from active galactic nuclei (AGN). By comparing a full-physics run versus one with jets turned off, we find causes...
