HST/WFPC2 and VLT/ISAAC observations of PROPLYDS in the giant HII region NGC 3603

, 1999
We report the discovery of three proplyd-like structures in the giant HII region NGC 3603. The emission nebulae are clearly resolved in narrow-band and broad-band HST/WFPC2 observations in the optical and broad-band VLT/ISAAC observations in the near ...

Microspherules Formed by Lightning Strikes

Meteoritics &Planetary Science, EarlyView.
Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.

Decomposing the Origin of TeV–PeV Emission from the Galactic Plane: Implications of Multimessenger Observations

The Astrophysical Journal Letters, 2023
High-energy neutrino and γ -ray emission has been observed from the Galactic plane, which may come from individual sources and/or diffuse cosmic rays.

Search for variable gamma-ray emission from the Galactic plane in the Fermi data

, 2012
High-energy gamma-ray emission from the Galactic plane above ~100 MeV is composed of three main contributions: diffuse emission from cosmic ray interactions in the interstellar medium, emission from extended sources, such as supernova remnants and pulsar

The Painterly Materiality of Clouds in Antony and Cleopatra and Hamlet

Renaissance Studies, EarlyView.
Abstract This article examines the cloud‐gazing scenes in Antony and Cleopatra and Hamlet through the lens of early modern artistic theory and material practices, particularly the art of limning. Building upon existing philosophical and poetic interpretations of Shakespearean clouds as metaphors for ephemerality and memory, the essay argues that the ...

Irradiation Investigation: Exploring the Molecular Gas in NGC 7293

Galaxies, 2020
Background: Many planetary nebulae retain significant quantities of molecular gas and dust despite their signature hostile radiation environments and energetic shocks.

Zinc abundances of planetary nebulae

, 2014
Zinc is a useful surrogate element for measuring Fe/H as, unlike iron, it is not depleted in the gas phase media. Zn/H and O/Zn ratios have been derived using the [Zn IV] emission line at 3.625um for a sample of nine Galactic planetary nebulae, seven of ...

S II emission lines in Planetary Nebulae [PDF]

Symposium - International Astronomical Union, 1997
Emission lines arising from transitions in S II have been detected in a wide variety of astronomical sources, including planetary nebulae (Hyung, Keyes & Aller 1995). These transitions are used to derive information on emitting plasmas parameters (Te, Ne) through diagnostic line ratios, although to calculate these quantities reliably, accurate ...

Jungian categories as modes of reading: The case of Graham Greene's The Heart of the Matter and Aldous Huxley's Time Must Have a Stop

Orbis Litterarum, Volume 81, Issue 2, Page 89-110, April 2026.
Abstract This essay advocates renewed attention toward Jungian literary criticism, emphasizing its unique and creative perspectives on both fictional worlds and on reading. A fresh turn to Jungian criticism offers, in particular, valuable insight for texts on the peripheries of the canon.
