The Isaac Newton Telescope Monitoring project: Stellar population in the IC 10 dwarf irregular galaxy [PDF]
Iranian Journal of Astronomy and Astrophysics, 2019 We have conducted an optical monitoring survey of IC 10 dwarf irregular galaxy in the Local Group, using the Isaac Newton Telescope (INT) with the wide-field camera (WFC), to identify the Asymptotic Giant Branch stars (AGBs).

People and Nature, EarlyView.Abstract As a result of expanding human populations and the anthropogenic modification of natural habitats, many wildlife populations are living in increasing proximity to humans. While this may provide benefits to some species through increased access to resources, sharing space and resources often leads to negative interactions or ‘conflict’ between ...

The Astrophysical JournalMeasuring the relation between star formation and galactic winds is observationally difficult. In this work we make an indirect measurement of the mass-loading factor (the ratio between the mass outflow rate and star formation rate) in low-mass galaxies ...

Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten
physica status solidi (b), EarlyView.This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

Nitrogen in irregular galaxies
The Astrophysical Journal, 1990 A study of nitrogen in giant H II regions located within low-abundance irregular galaxies is presented. Both observations and theoretical models are used to examine variations in the abundance of nitrogen relative to oxygen in these galaxies. Analysis of these and previously published observations suggests that the use of low spectral resolution is the

Stellar Populations of Dwarf Irregular Galaxies [PDF]
Symposium - International Astronomical Union, 1996 We recently completed two-color CCD photometry of resolved stars in 11 dwarf irregular galaxies (Hopp & Schulte-Ladbeck, 1995, A&AS 111, 527), selected because of their relative isolation from massive galaxies in the Kran-Korteweg – Tammann sample (1979, AN 300, 181).

Learning by helping: Evidence from Chinese brokerages' community CSR
Strategic Management Journal, EarlyView.Abstract Research Summary We propose that firms engaging in community corporate social responsibility (CSR) can acquire valuable local knowledge that improves their core operations. We test our proposition leveraging a unique context‐the Securities Association of China's pairing assistance scheme under the country's targeted poverty alleviation program.

Corvus A: A Low-mass, Isolated Galaxy at 3.5 Mpc
The Astrophysical Journal LettersWe report the discovery of Corvus A, a low-mass, gas-rich galaxy at a distance of approximately 3.5 Mpc, identified in DR10 of the Dark Energy Camera Legacy Imaging Survey during the initial phase of our ongoing SEmi-Automated Machine LEarning Search for
