Laboratory Spectral Characterization of Ribbeck Aubrite: Meteorite Sample of Earth-impacting Near-Earth Asteroid 2024 BX1

The Planetary Science Journal
Characterization of near-Earth objects (NEOs) is critical for Earth-impact hazard assessment. Particularly crucial to our physical understanding of NEOs are laboratory spectral measurements of meteorites as they are the best and most widely available ...

Comprehensive Study of Near-Earth Asteroid 2024 MK: Testing Planetary Encounters as a Source for Surface Refreshing

The Astrophysical Journal Letters
Near-Earth object 2024 MK was discovered on 2024 June 16, less than 2 weeks before it made a sub-lunar-distance close approach. This close approach provided an ideal opportunity to determine how planetary encounters affect asteroid surfaces in ...

Design and Simulation of TiN-Based Suspended Meander Kinetic Inductance Detectors (KIDs) for Visible and Near-Infrared Astronomy Applications

Journal of Low Temperature Physics
We report on simulations of a novel design of optical titanium nitride (TiN)- based Kinetic Inductance Detectors (KIDs) in order to improve their response to optical photons. We propose to separate the meander from the substrate to trap hot phonons generated by optical photons, preventing their rapid propagation through the substrate.

Asteroid Impact Hazard Warning from the Near-Earth Object Surveyor Mission

The Planetary Science Journal
NASA’s Near-Earth Object Surveyor mission, scheduled for launch in 2027 September, is designed to detect and characterize at least two-thirds of the potentially hazardous asteroids with diameters larger than 140 m in a nominal 5 yr mission. We describe a

Astro2020 Activity, Project of State of the Profession Consideration (APC) White Paper: All-Sky Near Infrared Space Astrometry. State of the Profession Considerations: Development of Scanning NIR Detectors for Astronomy

, 2019
Gaia is a revolutionary space mission developed by ESA and is delivering 5 parameter astrometry, photometry and radial velocities over the whole sky with astrometric accuracies down to a few tens of micro-arcseconds. A weakness of Gaia is that it only operates at optical wavelengths.

Pulling Back the Curtain on Shocks and Star Formation in NGC 1266 with Gemini-NIFS

The Astrophysical Journal
We present Gemini near-infrared integral field spectrograph K -band observations of the central 400 pc of NGC 1266, a nearby ( D ≈ 30 Mpc) post-starburst galaxy with a powerful multiphase outflow and a shocked interstellar medium.

Infrared Colors of Small Serendipitously Found Asteroids in the UKIRT Hemisphere Survey

The Astronomical Journal
The UKIRT Hemisphere Survey covers the northern sky in the infrared from 0° to 60° decl. Current data releases include both J and K bands, with H -band data forthcoming. Here, we present a novel pipeline to recover asteroids from this survey data.

The K s -band Luminosity Function of the Rich Cluster VC04 in the Vela Supercluster

The Astrophysical Journal
To learn more about the properties of the Vela Supercluster (VSCL), located behind the Milky Way at cz ∼ 18,000 km s ^−1 , we determine the K _s -band luminosity function (LF) of VC04, the richest known galaxy cluster in the VSCL, and two other VSCL ...
