Solar Low Energy X-ray Spectrometer on board Aditya-L1: Ground Calibration and In-flight Performance
The Solar Low-Energy X-ray Spectrometer (SoLEXS) on board India's Aditya-L1 mission was launched on 2 September 2023 and commenced solar observations on 13 December 2023 following successful aperture cover deployment. Operating from the Sun-Earth L1 Lagrange point, SoLEXS has been providing continuous Sun-as-a-star soft X-ray spectroscopy across 2-22 keV with 170 eV resolution at 5.9 keV and 1-second temporal cadence since 6 January 2024. The instrument employs two Silicon Drift Detectors with …

Normalized solutions for fractional Choquard equation with critical growth on bounded domain
In this work, we establish the multiplicity of positive solutions for the following critical fractional Choquard equation with a perturbation on the star-shaped bounded domain $$ \left\{ \begin{array}{lr} (-Δ)^s u = λu +α|u|^{p-2}u+ \left( \int\limits_Ω \frac{|u(y)|^{2^{*}_{μ,s}}}{|x-y|^ μ}\, dy\right) |u|^{2^{*}_{μ,s}-2}u\; \text{in} \; Ω,\\ u>0\; \text{in}\; Ω,\; \\ u = 0\; \text{in} \; \mathbb{R}^{N}\backslashΩ, \\ \int_Ω|u|^2 dx…
