Alignment and morphology of elliptical galaxies: the influence of the cluster tidal field
, 1994 We investigate two possible effects of the tidal field induced by a spherical cluster on its elliptical galaxy members: the modification of the ellipticity of a spherical galaxy and the isophotal alignment in the cluster radial direction of a misaligned ...

Astronomische Nachrichten, EarlyView.ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

Two-component mass models of the lensing galaxy in the quadruply imaged supernova iPTF16geu
The Open Journal of Astrophysics, 2020 The first resolved, multiply imaged supernova Type Ia, iPTF16geu, was observed 4 years ago, five decades after such systems were first envisioned. Because of the unique properties of the source, these systems hold a lot of promise for the study of galaxy

The Carnegie-Irvine Galaxy Survey. X. Bulges in Stellar Mass–based Scaling Relations
The Astrophysical Journal Supplement Series, 2022 We measure optical colors for the bulges of 312 disk galaxies from the Carnegie-Irvine Galaxy Survey and convert their previously available R -band structural parameters to stellar-mass parameters.

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,

A search for HI in five elliptical galaxies with fine structure [PDF]
, 2002 We report on VLA H I spectral line observations of five early-type galaxies classified as optically peculiar because of the presence of jets, ripples, or other optical fine structure.

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 ...

People and Nature, EarlyView.Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.
