We analyze two regions of the quiet Sun (35.6 × 35.6 Mm2) observed at high spatial resolution (lsim100 km) in polarized light by the IMaX spectropolarimeter on...
Debris Disks Can Contaminate Mid-infrared Exoplanet Spectra: Evidence for a Circumstellar Debris Disk around Exoplanet Host WASP-39
The signal from a transiting planet can be diluted by astrophysical contamination. In the case of circumstellar debris disks, this contamination could start in...
Decade time-scale modulation of low-mass X-ray binaries
Regular observations by the All-Sky Monitor aboard the Rossi X-ray Timing Explorer satellite have yielded well-sampled light curves with a time baseline of over...
This study presents the implementation of Multi-Criteria Decision-Making (MCDM) methodologies, particularly the fuzzy technique for order of preference by...
Deciphering Solar Coronal Heating: Energizing Small-scale Loops through Surface Convection
The solar atmosphere is filled with clusters of hot small-scale loops commonly known as coronal bright points (CBPs). These ubiquitous structures stand out in...
Deciphering the Activity and Quiescence of High-redshift Cluster Environments: ALMA Observations of Cl J1449+0856 at z = 2
We present Atacama Large Millimeter/submillimeter Array observations of the 870 μm continuum and CO(4-3) line emission in the core of the galaxy cluster Cl...
Deciphering the imprint of active galactic nucleus feedback in Seyfert galaxies: Nuclear-scale molecular gas deficits
We study the distribution of cold molecular gas in the circumunuclear disks (CND; r ≤ 200 pc) of a sample of 64 nearby (D L = 7 ‑ 45 Mpc) disk galaxies –...
Decoding the compositions of four bright r-process-enhanced stars
There has been a concerted effort in recent years to identify the astrophysical sites of the r-process that can operate early in the galaxy. The discovery of...
