A Census from JWST of Extreme Emission-line Galaxies Spanning the Epoch of Reionization in CEERS

The Astrophysical Journal
We present a sample of 1165 extreme emission-line galaxies (EELGs) at 4 < z < 9 selected using James Webb Space Telescope (JWST) NIRCam photometry in the Cosmic Evolution Early Release Science (CEERS) program.

Observations of O VI Emission from the Diffuse Interstellar Medium

, 2001
International audienceWe report the first Far-Ultraviolet Spectroscopic Explorer measurements of diffuse O VI (λλ1032, 1038) emission from the general diffuse interstellar medium outside of supernova remnants or superbubbles.

Detailed Study of Stars and Gas in a z = 8.3 Massive Merger with Extreme Dust Conditions

The Astrophysical Journal Letters
We present galaxy MACS0416-Y1 at z _spec = 8.312 as observed by the CAnadian NIRISS Unbiased Cluster Survey. MACS0416-Y1 has been shown to have extreme dust properties; thus, we study the physical properties and star formation histories of its resolved ...

Gamma ray lines from interstellar grains [PDF]

, 1976
The existence of very narrow (FWHM or approximately = 5 KeV) gamma ray line emission from interstellar grains is pointed out. The prime candidate for detection is the line at 6.129 Mev from O-16, but other very narrow lines could also be detected at 0 ...

The Galactic Center Lobe as an H ii Region

The Astrophysical Journal
The Galactic center lobe (GCL) is an object ∼1° across that is located north of the Galactic center. In the mid-infrared (MIR) the GCL appears as two 8.0 μ m filaments between which there is strong 24 μ m and radio continuum emission.

Molecular Clouds in the Outer Milky Way Disk: Sample, Integrated Properties, and Radial Trends with Galactocentric Radius

The Astrophysical Journal Supplement Series
We present a catalog of 32,162 ^12 CO molecular clouds that covers the northern outer Galactic plane ( l = [15°, 165°] and l = [195°, 230°], and b = [−5.°25, +5.°25]).

Forecasts and Statistical Insights for Line Intensity Mapping Cross-correlations: A Case Study with 21 cm × [C ii]

The Astrophysical Journal
Intensity mapping—the large-scale mapping of selected spectral lines without resolving individual sources—is quickly emerging as an efficient way to conduct large cosmological surveys. Multiple surveys covering a variety of lines (such as the hydrogen 21

FAST Search for Circumstellar Atomic Hydrogen. III. Planetary Nebulae at Galactic Latitudes ∣b∣ ≥ 10°

The Astronomical Journal
The detection of circumstellar atomic hydrogen (H i ) via the 21 cm line remains a persistent challenge in planetary nebula (PN) studies, primarily due to contamination from ubiquitous interstellar H i 21 cm emission. In this paper, we report the results
