An automated polarimeter and its use in the study of active galaxies [PDF]

, 1996
In this thesis I present the design and development of an automated polarimeter for use in mapping the percentage levels and position angles of linearly polarized light from extended astronomical objects.

GloBIAS survey results – An insight into the global bioimage analysis community

Journal of Microscopy, EarlyView.
Abstract There is a global need for bioimage analysis (BIA) as advances in life sciences increasingly rely on cutting‐edge imaging systems that have dramatically expanded the complexity and dimensionality of biological images. Turning these data into scientific discoveries requires scientists with effective data management skills and knowledge of state‐

Galaxy collisions

Physics Reports, 1999
Theories of how galaxies, the fundamental constituents of large-scale structure, form and evolve have undergone a dramatic paradigm shift in the last few decades. Earlier views were of rapid, early collapse and formation of basic structures, followed by slow evolution of the stellar populations and steady buildup of the chemical elements.

Bioimage management and analysis in Galaxy: Tools, workflows, training, and community practices

Journal of Microscopy, EarlyView.
ABSTRACT Image analysis in the life sciences is constrained by fragmented software ecosystems, heterogeneous data formats, and limited reproducibility. These barriers hinder the reuse of image analysis methods and the sustainability of tools. In this article, we describe how the Galaxy platform enables FAIR (Findable, Accessible, Interoperable, and ...

The effect of the environment on the evolution of galaxy colours [PDF]

, 2006
In chapter 1 of this thesis, I give a brief overview of the birth of modern cosmology and the growth of the current paradigm. I then go on to describe the different types of galaxies, the star formation rates within them and give some notes about galaxy ...

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

Journal of Clinical Nursing, EarlyView.
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 ...

Tidal Structures Around Edge-On Galaxies in Deep Imaging Surveys

Galaxies
We present a statistical study of low-surface-brightness (LSB) tidal structures in two large samples of edge-on disk galaxies. Our primary sample comprises 5606 galaxies from the Edge-on Galaxies In SDSS (EGIS) catalog, analyzed using imaging from the ...

The clustering and number counts of galaxies [PDF]

, 2001
We present a Curtis Schmidt CCD survey of two strips of the sky overlapping with the NGC and SGC 2dFGRS fields. When this survey is used in conjunction with data from the APM Galaxy Survey, DUKST, 2dFGRS and 2MASS, we find that there is a hole in the SGC

Photochemical effects of Mars‐like UV irradiation on carboxylic acids in carbonaceous chondrites and expectations for abiotic background organics on Mars

Meteoritics &Planetary Science, EarlyView.
Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an
