Abstract We present simultaneous XMM–Newton and NuSTAR observations of the repeat changing-look AGN NGC 1566, which dramatically increased in brightness IR to X-ray bands 2018. The broad-band spectrum was taken at peak outburst is typical Seyfert 1 AGN. shows a soft excess, Compton hump, warm absorption reflection, ruling out tidal disruption as cause demonstrating that ‘standard’ accretion disk can develop very rapidly. high-resolution grating reveals has launched ∼500 km s−1 outflow,...
Polycyclic aromatic hydrocarbons (PAHs) are abundantly present in the interstellar medium and our solar system lock up a significant fraction of cosmic carbon. They found to be interplanetary dust particles. Impact ionization mass spectrometers on future space missions can detect such particles assess their composition; it is essential understand impact behavior PAH-based impinging metal targets at relevant velocities. To date, studies fast-moving organic-rich have been limited vinyl...
Lunar Ice Cube, scheduled to be launched on ARTEMIS I in late 2021, is a deep space cubesat mission with the goals of demonstrating 1) cubesat-scale instrument (BIRCHES) capable addressing NASA HEOMD Strategic Knowledge Gaps related lunar volatile distribution (abundance, location, and transportation physics water ice), 2) propulsion, via Busek BIT 3 RF Ion engine. The will also demonstrate AIM/IRIS microcryocooler for first time space. BIRCHES integration nearly complete, several changes...

The broad-band spectrum was taken at peak outburst is typical Seyfert 1 AGN. shows a soft excess, Compton hump, warm absorption reflection, ruling out tidal disruption as cause demonstrating that 'standard' accretion disk can develop very rapidly. high resolution grating reveals has launched ~ 500 km/s outflow, photoionised...
The Interstellar Mapping and Acceleration Probe (IMAP) is scheduled to launch in 2025, be stationed at the Sun-Earth L1 Lagrange point with a combination of 10 in-situ remote sensing instruments. A primary science goal of  IMAP improve our understanding composition properties local interstellar medium. medium contains plasma, magnetic fields, neutral atoms, cosmic rays, dust which all influence heliosphere through interconnected time-dependent multi-scale processes. Dust Experiment...
