Resolving Systematics in Deep Wide-field Imaging for Low Surface Brightness Astronomy

open access: yes
The low surface brightness Universe is a treasure trove of extraordinarily interesting phenomena that are virtually unexplored. With advances in hardware and software in recent decades, astronomers are now capable of probing faint diffuse emission below ...

Numerical modeling of the magnetosphere with data based internal magnetic field and arbitrary magnetopause

open access: yes, 2011
We present a new model of the magnetospheric magnetic field. Using the finite element method, ChapmanFerraro problem is solved numerically in the considered approach.

An Introduction to the 'Special Volume Spectroscopy and Chemometrics in R'

open access: yes
This special volume collates ten issues under the rubric "Spectroscopy and Chemometrics in R". In so doing, it provides an overview of the breadth, depth and state of the art of R-based software projects for spectroscopy and chemometrics applications ...

Development and Application of a Situated Apprenticeship Approach to Professional Development of Astronomy Instructors

open access: yes, 2008
Professional development for astronomy instructors largely focuses on enhancing their understanding of the limitations of professor-centered lectures while also increasing awareness and better implementation of learning strategies that promote a learner ...

Atmospheric Limitations for High-frequency Ground-based Very Long Baseline Interferometry

open access: yesThe Astrophysical Journal
Very long baseline interferometry (VLBI) provides the highest-resolution images in astronomy. The sharpest resolution is nominally achieved at the highest frequencies, but as the observing frequency increases, so too does the atmospheric contribution to ...

Peaky Finders: Characterizing Double-peaked Type IIb Supernovae in Large-scale Live-stream Photometric Surveys

open access: yesThe Astrophysical Journal
We present the first photometric population study of double-peaked Type IIb supernovae (SNe IIb). SNe IIb are produced from the core collapse of massive stars whose outermost hydrogen layer has been partially stripped prior to explosion.

The Eclipsing Binaries via Artificial Intelligence. II. Need for Speed in PHOEBE Forward Models

open access: yesThe Astrophysical Journal Supplement Series
In modern astronomy, the quantity of data collected has vastly exceeded the capacity for manual analysis, necessitating the use of advanced artificial intelligence (AI) techniques to assist scientists with the most labor-intensive tasks.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

The THESEUS Space Mission and the Infrared Telescope Calibration Unit

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an
