  • Mapping dusty galaxy growth at z > 5 with FRESCO: detection of Hα in submm galaxy HDF850.1 and the surrounding overdense structures
    We report the detection of a 13 $\sigma$ H $\alpha$ emission line from HDF850.1 at $z=5.188\pm 0.001$ using the FRESCO (First Reionization Era Spectroscopically Complete Observations) NIRCam F444W grism observations. Detection of H $\alpha$ in HDF850.1 is noteworthy, given its high far-infrared (IR) luminosity, substantial dust obscuration, and the

  • Discovery and Characterization of an Eccentric, Warm Saturn Transiting the Solar Analog TOI-4994
    We present the detection and characterization of TOI-4994b (TIC 277128619b), a warm Saturn-sized planet discovered by the NASA Transiting Exoplanet Survey Satellite. TOI-4994b transits a G-type star (V = 12.6 mag) with a mass, radius, and effective temperature of M ⋆ = 1.00 5 ‑ 0.061 + 0.064 M ⊙ , R ⋆ = 1.05 5 ‑ 0.037 + 0.040 R ⊙ , and T eff = 5640

  • Advanced Phase Diversity Method for telescope static aberration compensation
    Accurate calibration is essential for high-performance Adaptive Optics (AO) systems in astronomy. This paper presents a novel methodology for AO systems calibration that preserves the optical path integrity while achieving high-quality results. By eliminating the need for optical modifications, this approach simplifies system complexity and

  • A reference framework for extremely metal-poor OB star studies: calibrations for stellar parameters and intrinsic colours
    We provide the first reference framework for extremely metal-poor (XMP) OB-type stars. We parsed a grid of 0.10 $Z_{\odot }$FASTWIND models, covering the parameter space of O stars and early-B supergiants, through contemporary spectral classification criteria to deliver a calibration of key stellar properties as a function of spectral type, and

  • X-Ray and Optical Polarization Aligned with the Radio Jet Ejecta in GX 339–4
    We present the first X-ray polarization measurements of GX 339–4. IXPE observed this source twice during its 2023–2024 outburst, once in the soft-intermediate state and again during a soft state. The observation taken during the intermediate state shows a significant (4σ) polarization degree P X = 1.3% ± 0.3% and polarization angle θ X = ‑74° ± 7°

  • Why do some ultra diffuse Galaxies have rich globular cluster systems?
    Some ultra diffuse galaxies (UDGs) reveal many more globular clusters (GCs) than classical dwarf galaxies of the same stellar mass. These UDGs, with a mass in their GC system ( $M_{\rm GC}$) approaching 10 per cent of their host galaxy stellar mass ( $M_{\ast }$), are also inferred to have high halo mass to stellar mass ratios ( $M_{\rm halo}/M_{
