We present deep K s-band imaging of the extreme T subdwarf CWISE J221706.28‑145437.6. Using the new photometry, we construct its spectral energy distribution and find this object exhibits exceptionally strong collision-induced absorption in the H and K band. The comparison with the nearest benchmark extreme T subdwarf WISEA J181006.18‑101000.5

Luminous and Ultra-luminous IR galaxies ((U)LIRGs) are critical for investigating feedback mechanisms due to a combination of intense star formation (SF) episodes and active galactic nuclei (AGN), particularly in the context of complex galaxy interactions. We conduct a detailed analysis of the II ZW 096 merging system using the Multi-Unit

With some 14, 15 and 29 years of HMI, MDI and GONG observations, respectively, we have reached a new milestone in acquiring almost three decades of nearly continuous helioseismic observations. Moreover, an alternative fitting methodology to the respective projects global helioseismic pipeline has produced tables of individual mode frequencies based
