The location of the broad HI absorption in 3C305: clear evidence for a jet-accelerated neutral outflow

, 2005
We present high-spatial resolution 21-cm HI VLA observations of the radio galaxy 3C305 (z=0.041). These new high-resolution data show that the ~1000 km/s broad HI absorption, earlier detected in low-resolution WSRT observations, is occurring against the ...

Comparative Insights and Overlooked Factors of Interphase Chemistry in Alkali Metal‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review presents a comparative analysis of Li‐, Na‐, and K‐ion batteries, focusing on the critical role of electrode–electrolyte interphases. It especially highlights overlooked aspects such as SEI/CEI misconceptions, binder effects, and self‐discharge relevance, emphasizing the limitations of current understanding and offering strategies for ...

Multiscale Perspectives on Perovskite Instability: From Atomistic Deformation to Device Degradation in Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.

A New Look at the Kinematics of Neutral Hydrogen in the Small Magellanic Cloud

The Astrophysical Journal, 2004
We have used the latest HI observations of the Small Magellanic Cloud (SMC), obtained with the Australia Telescope Compact Array and the Parkes telescope, to re-examine the kinematics of this dwarf, irregular galaxy. A large velocity gradient is found in the HI velocity field with a significant symmetry in iso-velocity contours, suggestive of a ...

Metallicity Mapping of the Ionized Diffuse Gas at the Milky Way Disk–Halo Interface

The Astrophysical Journal
Metals in the diffuse, ionized gas at the boundary between the Milky Way’s interstellar medium (ISM) and circumgalactic medium, known as the disk–halo interface (DHI), are valuable tracers of the feedback processes that drive the Galactic fountain ...

21 Cm Hydrogen-Line Survey Of The Large Magellanic Cloud Ii. Distribution And Motions Of Neutral Hydrogen [PDF]

Australian Journal of Physics, 1966
The 21 cm hydrogen-line data from a survey of the Large Magellanic Oloud with a 14',5 aerial beam have been simplified into distributions of intensities and radial velocities at profile peaks. Fifty-two large HI complexes of mean diameter 575 pc, density I hydrogen atom per cm3, and mass 4 X 106M o have been delineated.

A New High-latitude H i Cloud Complex Entrained in the Northern Fermi Bubble

The Astrophysical Journal Letters
We report the discovery of 11 high-velocity H i clouds at Galactic latitudes of 25°–30°, likely embedded in the Milky Way’s nuclear wind. The clouds are detected with deep Green Bank Telescope 21 cm observations of a 3 $\mathop{.}\limits^{\unicode{x000b0}

Compact Galactic Neutral Hydrogen Clouds in the GALFA-HI Survey

, 2014
The more sensitive the observations, the more complex the gas in our Galaxy appears. Since the detection of neutral hydrogen in 1951, each new survey has revealed new structure. Using the GALFA-HI survey, we have discovered five populations of compact neutral hydrogen clouds.

Neutral hydrogen absorption in the quasar 3C 268.4 - Possible evidence for galactic halo clouds

The Astrophysical Journal, 1983
We have detected neutral hydrogen absorption at 21 cm wavelength in the quasar-galaxy pair 3C 268.4/NGC 4138. The absorption spectrum exhibits two features which are separated by 65 and -120 km s/sup -1/, respectively, from the center velocity of 880 km s/sup -1/ of the neutral hydrogen emission profile from NGC 4138. The line of sight of the quasar 3C
