Solid Harmonic Wavelet Bispectrum for Image Analysis. [PDF]
Adv Sci (Weinh)The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Supernova Remnants in the Irregular Galaxy NGC 4449
The Astrophysical Journal, 2023 Abstract The nearby irregular galaxy NGC 4449 has a star formation rate of ∼0.4M ☉ yr−1 and should host of order 70 supernova remnants (SNRs) younger than 20,000 yr, a typical age for SNRs expanding into an interstellar medium (ISM) with a density of 1 cm−3 to reach the radiative phase.

Magnetic Fields in Irregular Galaxies [PDF]
Proceedings of the International Astronomical Union, 2008 Magnetic fields are an important component of the interstellar medium, especially in low-mass galaxies like irregulars where the magnetic pressure may be significant. However, few irregular galaxies have observed magnetic field structures. Using the VLA, the GBT, and the ATCA, we have observed several irregular galaxies in the radio continuum to ...

Early assembly of the most massive galaxies [PDF]
, 2009 The current consensus is that galaxies begin as small density fluctuations in the early Universe and grow by in situ star formation and hierarchical merging(1).

Lopsidedness in dwarf irregular galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2000 We quantify the amplitude of the lopsidedness, the azimuthal angular asymmetry index, and the concentration of star forming regions, as represented by the distribution of the H$α$ emission, in a sample of 78 late-type irregular galaxies. We bin the observed galaxies in two groups representing blue compact galaxies (BCDs) and low surface brightness ...

GALACTIC WINDS IN IRREGULAR STARBURST GALAXIES [PDF]
, 2001 In this paper we present some results concerning the study of the development of galactic winds in blue compact galaxies. In particular, we model a situation very similar to that of the galaxy IZw18, the most metal poor and unevolved galaxy known locally.
