Origin of an orbiting star around the galactic supermassive black hole
The tremendous tidal force that is linked to the supermassive black hole (SMBH) at the center of our galaxy is expected to strongly subdue star formation in its vicinity.

Mapping the Decline with Redshift of Dusty Star-forming Galaxies Using JWST and SCUBA-2
We use JWST NIRCam observations of the massive lensing cluster field A2744 to develop a red galaxy selection of f _F444W > 1 μ Jy and f _F444W / f _F150W > 3.5 that picks out all nine >4.5 σ Atacama Large Millimeter/submillimeter Array 1.1 or 1.2 mm ...

The effect of the impact of comet Shoemaker Levy‐9 on Jupiter's aurorae [PDF]
We present infrared spectra and images of the jovian aurorae taken at wavelengths sensitive to the H-3(+) molecular ion during the period around the impact of Comet Shoemaker Levy-9.

Correlating Changes in Spot Filling Factors with Stellar Rotation: The Case of LkCa 4
We present a multi-epoch spectroscopic study of LkCa 4, a heavily spotted non-accreting T Tauri star. Using SpeX at NASA’s Infrared Telescope Facility (IRTF), 12 spectra were collected over five consecutive nights, spanning ≈1.5 stellar rotations.

Exploring the Extremes: Characterizing a New Population of Old and Cold Brown Dwarfs
Mapping out the populations of thick disk and halo brown dwarfs is important for understanding the metallicity dependence of low-temperature atmospheres and the substellar mass function.

Second-Order Gauge-Invariant Cosmological Perturbation Theory: Current Status
The current status of the recent developments of the second-order gauge-invariant cosmological perturbation theory is reviewed. To show the essence of this perturbation theory, we concentrate only on the universe filled with a single scalar field ...

Cooperative polariton dynamics in feedback-coupled cavities
Rabi oscillations of magnons typically do not have few photon control of single spin quantum systems. Here, the authors use a feedback cavity architecture to increase magnon-photon cooperativity, enabling increased control of light-matter interactions in
