Properties of cD Galaxies [PDF]
Symposium - International Astronomical Union, 1987 cD galaxies are the most luminous galaxies in the universe. They are characterized by a surface brightness profile that falls off more slowly with radius than most elliptical galaxies. In most respects D galaxies are a continuous extrapolation from other ellipticals: their M/L and their colors are comparable to other ellipticals, their inner parts are ...

The host of the SN-less GRB 060505 in high resolution
, 2014 The spiral host galaxy of GRB 060505 at z=0.089 was the site of a puzzling long duration burst without an accompanying supernova. Studies of the burst environment by Th\"one et al.

Beyond mass: detecting secondary halo properties with galaxy-galaxy lensing
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACTSecondary halo properties beyond mass, such as the mass accretion rate (MAR), concentration, and the half mass scale, are essential in understanding the formation of large-scale structure and dark matter haloes. In this paper, we study the impact of secondary halo properties on the galaxy-galaxy lensing observable, ΔΣ.

Advanced Materials, EarlyView.A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

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,

Exploring the Mass–Metallicity Relationships with the DESI BGS and ELG Samples
The Astronomical JournalThe mass–metallicity relation (MZR) serves as a cornerstone for understanding the chemical evolution of galaxies by correlating the stellar mass of galaxies with their gas-phase metallicity.

On the Effects of Local Environment on Active Galactic Nucleus (AGN) in the Horizon Run 5 Simulation
The Astrophysical Journal, 2023 We use the Horizon Run 5 cosmological simulation to study the effect of galaxy intrinsic properties and the local environment on active galactic nuclei (AGNs) characterized by their threshold of the accretion rate.

Modeling vertical structure in circular velocity of spiral galaxy NGC 4244
, 2015 We study the vertical gradient in azimuthal velocity of spiral galaxy NGC 4244 in a thin disk model. With surface density accounting for the rotation curve, we model the gradient properties in the approximation of quasi-circular orbits and find the ...
