The Globular Cluster Luminosity Function and Specific Frequency in Dwarf Elliptical Galaxies
, 2007 The globular cluster luminosity function, specific globular cluster frequency, S_N, specific globular cluster mass, T_MP, and globular cluster mass fraction in dwarf elliptical galaxies are explored using the full 69 galaxy sample of the HST WFPC2 Dwarf ...

In Situ Analysis of Jupiter's Broadband Kilometric Auroral Radio Emissions With Juno
Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.Abstract Among the zoo of Jovian auroral radio emissions, the broadband kilometric (bKOM) component has been the least studied. Taking advantage of Juno in situ measurements within the auroral regions, we surveyed the Juno/Waves radio observations over the 60 first orbits to identify 7 bKOM source candidates.

Giant Halos in Dwarf Irregular Galaxies vs. Dwarf Elliptical Galaxies
, 2005 We present a discovery of a giant stellar halo in NGC 6822, a dwarf irregular galaxy in the Local Group. This halo is mostly made of old red giants, showing striking features: 1) it is several times larger than the main body of the galaxy seen in the ...

Selection of Biofortified Sweet Potato (Ipomoea batatas L.) Genotypes in Response to Drought Stress
Journal of Agronomy and Crop Science, Volume 211, Issue 3, May 2025.ABSTRACT The development of orange‐ and purple‐fleshed sweet potato genotypes with high nutritional quality and drought tolerance is paramount in the face of climate changes and exponential human population growth. Therefore, the objective was to select biofortified sweet potato genotypes tolerant to drought. Eight progenies developed by the NEOSC‐UFSC

The Effect of Superpositions on the Planetary Nebula Luminosity Function
The Astrophysical Journal, 2023 Planetary nebula (PN) surveys in systems beyond ∼10 Mpc often find high-excitation, point-like sources with [O iii ] λ 5007 fluxes greater than the apparent bright-end cutoff of the planetary nebula luminosity function (PNLF).

From voids to filaments: environmental transformations of galaxies in the SDSS
, 2017 We investigate the impact of filament and void environments on galaxies, looking for residual effects beyond the known relations with environment density. We quantified the host environment of galaxies as the distance to the spine of the nearest filament,

Volume measurement of microparticles using SEM photogrammetry and 3‐D reconstruction
Meteoritics &Planetary Science, Volume 60, Issue 5, Page 1227-1235, May 2025.Abstract In this paper, we introduce a method for volume measurement of microparticles that includes scanning electron microscope photogrammetry with 3‐D model construction. Our results show that our method limits the volume uncertainty to ±10%, which is a significant improvement compared to previous methods (which likely overestimated volume by 100 ...

Near-IR TRGB Distance to Dwarf Elliptical Galaxy NGC 147 [PDF]
Journal of Astronomy and Space Sciences, 2007 We report the distance modulus of nearby dwarf elliptical galaxy NGC 147 estimated from the Tip of Red-giant Branch (TRGB) method applying to the color-magnitude diagrams and luminosity functions in the near-infrared JHK bands.

Lopsidedness of cluster galaxies in modified gravity
, 2010 We point out an interesting theoretical prediction for elliptical galaxies residing inside galaxy clusters in the framework of modified Newtonian dynamics (MOND), that could be used to test this paradigm.

Clustering around radio galaxies at z~1.5 [PDF]
, 2002 The importance of studying old elliptical galaxies at redshift z ~ 1.5 is reviewed, considering both what can be learned by extending studies of the evolution of cluster galaxy scaling relations to earlier cosmic epochs, and the age-dating of old ...
