  • Rapid mid-infrared spectral timing with JWST: GRS 1915+105 during an MIR-bright and X-ray-obscured state
    We present mid-infrared (MIR) spectral-timing measurements of the prototypical Galactic microquasar GRS 1915+105. The source was observed with the Mid-Infrared Instrument (MIRI) onboard JWST in June 2023 at an MIR luminosity $L_{\rm MIR}$ $\approx$ 10 $^{36}$ erg s $^{-1}$ exceeding past infrared levels by about a factor of 10. In contrast, the X

  • OrCAS: Origins, Compositions, and Atmospheres of Sub-Neptunes. I. Survey Definition
    Sub-Neptunes—volatile-rich exoplanets smaller than Neptune—are intrinsically the most common type of planet known. However, the formation and nature of these objects, as well as the distinctions between subclasses (if any), remain unclear. Two powerful tools to tease out the secrets of these worlds are measurements of (i) atmospheric composition

  • MOA-2022-BLG-033Lb, KMT-2023-BLG-0119Lb, and KMT-2023-BLG-1896Lb: Three low mass-ratio microlensing planets detected through dip signals
    Aims. We examined the anomalies in the light curves of the lensing events MOA-2022-BLG-033, KMT-2023-BLG-0119, and KMT- 2023-BLG-1896. These anomalies share similar traits: they occur near the peak of moderately to highly magnified events and display a distinct short-term dip feature. Methods. We conducted detailed modeling of the light curves to

  • 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

  • GD-1 Stellar Stream and Cocoon in the DESI Early Data Release
    We present ∼115 new spectroscopically identified members of the GD-1 tidal stream observed with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We confirm the existence of a "cocoon," which is a broad (FWHM ∼ 2 932 ∼ 460 pc) and kinematically hot (velocity dispersion, σ ∼ 5–8 km s ‑1) component that surrounds a narrower (FWHM ∼ 0 353 ∼

  • 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
