The impact of selection criteria on the properties of green valley galaxies

Astronomy & Astrophysics
Context. The bi-modality in the distribution of galaxies usually obtained from colour-colour or colour-stellar mass (absolute magnitude) diagrams has been studied to determine the difference between galaxies in the blue cloud and in the red sequence, as ...

The clustering of dark matter, haloes & galaxies [PDF]

, 2008
In this thesis I study the spatial distribution of galaxies, haloes and dark matter particles using a suite of state-of-art cosmological N-body simulations of the growth structure in the Universe.

Nurses' Visual Attention During Initial Observation of Patients With Suspected Pneumonia: An Observational Pupillometry Study

Japan Journal of Nursing Science, Volume 23, Issue 4, October 2026.
ABSTRACT Aim Observation requires selective attention to visual information acquired through gaze. Measuring pupil diameter, an index of attention, we examined skilled and novice nurses during the initial assessment of a patient urgently admitted with suspected community‐acquired pneumonia.

Dwarf and Intermediate-mass Galaxies in MaNGA: Evidence for Different Evolutionary Trends

The Astrophysical Journal
We investigate the interplay between morphology, specific star formation rate (sSFR), and local environment using a sample of 7408 galaxies from the fourth-generation Sloan Digital Sky Survey Mapping Nearby Galaxies at Apache Point Observatory survey ...

Interventions to Reduce Loneliness in Informal Caregivers of People With Dementia: A Systematic Review

Journal of Clinical Nursing, Volume 35, Issue 10, Page 4124-4136, October 2026.
ABSTRACT Aim To summarize the current evidence on reducing loneliness among informal caregivers of people with dementia, such as family members or friends. Design A systematic review. Methods The methodological quality was evaluated using the revised Cochrane risk‐of‐bias tool for randomized controlled trials and the revised JBI critical appraisal ...

Galaxies Caught in Transition: The Role of Group Environment in Shaping the Mass–Size Relation in the Local Universe

The Astrophysical Journal
The stellar mass–size relation is a sensitive probe of how environment shapes galaxy structure. We analyse this relation in the local Universe for galaxies in compact groups (CGs), low-mass groups ( M _vir ≤ 10 ^13 M _⊙ ), and high-mass groups, comparing

Internal Extinction in the SDSS Late-Type Galaxies

, 2008
We study internal extinction of late-type galaxies in the Sloan Digital Sky Survey. We find that the degree of internal extinction depends on both the concentration index c and K_s-band absolute magnitude M_K. We give simple fitting functions for internal extinction. In particular, we present analytic formulae giving the extinction-corrected magnitudes

Cosmic Radiation Dose‐Rates for Civil Aviation in the Middle East: Vertical Structure, Solar Modulation, and Comparison With Models

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract High‐altitude balloon measurements were conducted over southern Israel (30°35′N, 34°45′E; 850 m a.s.l., geomagnetic rigidity cutoff 10.3 GV) to characterize the vertical profiles of atmospheric ionization and radiation up to ∼35 km. Six balloon launches between October 2014 and August 2016 recorded the variability of atmospheric ionization ...

Tip of the Red Giant Branch Distances to NGC 1316, NGC 1380, NGC 1404, and NGC 4457: A Pilot Study of a Parallel Distance Ladder Using Type Ia Supernovae in Early-type Host Galaxies

The Astrophysical Journal
Although Type Ia supernovae (SNe Ia) are found in all galaxies types, recent local Hubble constant measurements have disfavored using SNe Ia in early-type/quiescent galaxies, aiming instead for better consistency with SNe Ia in star-forming/late-type ...
