Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

The Shocking Features in the Closest Rich Galaxy Cluster Norma

open access: yesThe Astrophysical Journal
The merger shocks generated by the collision of galaxy clusters elevate the pressure within the intracluster medium, significantly influencing the evolution of embedded cluster galaxies.

Detailed Shapes of the Line-of-sight Velocity Distributions in Massive Early-type Galaxies from Nonparametric Spectral Models

open access: yesThe Astrophysical Journal, 2023
We present the first systematic study of the detailed shapes of the line-of-sight velocity distributions (LOSVDs) in nine massive early-type galaxies (ETGs) using the novel nonparametric modeling code WINGFIT.

About the linearity of the color-magnitude relation of early-type galaxies in the Virgo cluster [PDF]

open access: yes, 2013
We revisit the color-magnitude relation (CMR) of the Virgo cluster early-type galaxies in order to explore its alleged non-linearity. To this aim, we reanalyze the relation already published from data obtained within the ACS Virgo Cluster Survey of the ...

Controlling 3D Contractility via Engineered Fibrous Hydrogel Composites

open access: yesAdvanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
A tunable composite contractile assembly (CCA) is developed that can permit or resist contraction without changing cell‐adhesion and density, unlike collagen whose inherent coupling of these ECM cues limits its use as a platform in contractility studies.

Comparing Globular Cluster System Properties with Host Galaxy Environment

open access: yesThe Astrophysical Journal, 2023
We present Hubble Space Telescope photometry in the optical (F475X) and near-infrared (F110W) bands of the globular cluster (GC) systems of the inner halos of a sample of 15 massive elliptical galaxies.

On the Origin and Evolution of the Intra-Cluster Light: A Brief Review of the Most Recent Developments

open access: yesGalaxies, 2021
Not all the light in galaxy groups and clusters comes from stars that are bound to galaxies. A significant fraction of it constitutes the so-called intracluster or diffuse light (ICL), a low surface brightness component of groups/clusters generally found

The Principal Axis of the Virgo Cluster [PDF]

open access: yes, 2000
Using accurate distances to individual Virgo cluster galaxies obtained by the method of Surface Brightness Fluctuations, we show that Virgo's brightest ellipticals have a remarkably collinear arrangement in three dimensions.

BRIGHTEST CLUSTER GALAXIES AND CORE GAS DENSITY IN REXCESS CLUSTERS [PDF]

open access: yesThe Astrophysical Journal, 2010
We investigate the relationship between brightest cluster galaxies (BCGs) and their host clusters using a sample of nearby galaxy clusters from the Representative XMM Cluster Structure Survey (REXCESS). The sample was imaged with the Southern Observatory for Astrophysical Research (SOAR) in R band to investigate the mass of the old stellar population ...

A Two‐Step Artificial Intelligence Approach for Correcting Space Weathering Effects in the Lunar Reconnaissance Orbiter Diviner Christiansen Feature Image

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Space weathering substantially distorts the Christiansen feature (CF) observed by Lunar Reconnaissance Orbiter (LRO) Diviner thermal infrared radiometer, obscuring the intrinsic compositional and thermophysical signals of lunar surface silicate minerals.
