Infrared Properties of Star-forming Dwarf Galaxies. I. Dwarf Irregular Galaxies in the Local Volume [PDF]
The Astronomical Journal, 2005 A sample of 34 dwarf irregular galaxies in the Local Volume, most nearer than 5 Mpc, has been imaged in the near-infrared (NIR) in J and K_s at CFHT in Hawaii and OAN-SPM in Mexico. In CFHT images, stars brighter than M_Ks=-7.5 were resolved. In most cases, the resolved population represents less than 5% of the total NIR flux in K_s.

Mass‐Loss, Composition and Observational Signatures of Stellar Winds From X‐Ray Bursts
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT X‐Ray bursts (XRBs) are powerful thermonuclear events on the surface of accreting neutron stars (NSs), which can synthesize intermediate‐mass elements. Although the high surface gravity prevents an explosive ejection, a small fraction of the envelope may be ejected by radiation‐driven winds.

Chemodynamical Simulations of Dwarf Galaxy Evolution
Advances in Astronomy, Volume 2014, Issue 1, 2014., 2014 In this review I give a summary of the state of the art for what concerns the chemo‐dynamical numerical modelling of galaxies in general and of dwarf galaxies in particular. In particular, I focus my attention on (i) initial conditions, (ii) the equations to solve; (iii) the star formation process in galaxies, (iv) the initial mass function, (v) the ...

The Astrophysical Journal, 2023 The presence of transitional dwarf galaxies in filaments and cluster outskirts may be closely related to preprocessing in the filament; however, the underlying mechanism is not yet comprehensively understood.

OLD GLOBULAR CLUSTERS IN MAGELLANIC-TYPE DWARF IRREGULAR GALAXIES
The Astronomical Journal, 2008 We present a study of the old globular clusters (GC) using archival F606W and F814W HST/ACS images of 19 Magellanic-type dwarf Irregular (dIrr) galaxies found in nearby (2 - 8 Mpc) associations of only dwarf galaxies. All dIrrs have absolute magnitudes fainter than or equal to the SMC (Mv = -16.2 mag).

Commodity risk assessment of Betula pendula and Betula pubescens plants from the UK
EFSA Journal, Volume 22, Issue 11, November 2024.Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by plants of Betula pendula and B.

Astronomical Signatures of Dark Matter
Advances in High Energy Physics, Volume 2014, Issue 1, 2014., 2014 Several independent astronomical observations in different wavelength bands reveal the existence of much larger quantities of matter than what we would deduce from assuming a solar mass to light ratio. They are very high velocities of individual galaxies within clusters of galaxies, higher than expected rotation rates of stars in the outer regions of ...
