Microlensing, Brown Dwarfs and GAIA

open access: yes, 2018
The GAIA satellite can precisely measure the masses of nearby brown dwarfs and lower main sequence stars by the microlensing effect. The scientific yield is maximised if the microlensing event is also followed with ground-based telescopes to provide ...

When Thriving for More Collapses the System: The Academic Reproduction of Uncaring Structures

open access: yesBritish Journal of Management, EarlyView.
Abstract This essay argues that the widening gap between aspirational aims and visionary orientations and the prevailing practices in neoliberal academia stems from deeper, historically rooted, market‐based logics shaping our institutions, increasingly governed by economic values and academic subjectivities therein.

Desegregationist Pan‐African Spiritual Strivings: Du Bois, the Black Church and the Critique of Imperialism*

open access: yesJournal of Religious History, EarlyView.
Abstract This article argues that W. E. B. Du Bois grounded his seminal conceptualisation of “the Negro church” in a Pan‐Africanist challenge to how Christian reformers and missionaries' usage of “Darkest Africa” as a metaphor for modern urban vice and poverty denigrated Africa and the African diaspora while promoting a segregated, imperialist version ...

South Asian Bodies at British Borders in the 1970s: From the Ugandan Asian ‘Stateless Husbands’ to ‘Virginity Testing’

open access: yesGender &History, EarlyView.
ABSTRACT This article looks at two critical moments in British immigration – the case of the ‘stateless’ Ugandan Asian husbands, whose wives successfully argued for their entry in Britain in 1973 and the ‘virginity test’ performed on Mrs K at Heathrow Airport in 1979.

An Informed and Systematic Method to Identify Variable Mid-L Dwarfs

open access: yesThe Astrophysical Journal
Most brown dwarfs show some level of photometric or spectral variability. However, finding the most variable dwarfs more suited for a thorough variability monitoring campaign remained a challenge until a few years ago with the design of spectral indices ...

REPAIR AND RECONSTRUCTION FOR URBAN COMMONING: The Making of the Liberated Spaces in Naples

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Commoning requires repair. Where capitalist logics of accumulation, enclosure and exclusion produce abandoned space through the city, urban commoners remake that space to serve the needs of inhabitants. Without hiding the paradoxes and risks of repair, based on years‐long ethnography in the Liberated Spaces in Naples, Italy, we demonstrate how

An Aligned Very-low-mass Star Orbiting an M Dwarf and Obliquity Patterns across Giant Planets, Brown Dwarfs, and Binary Stars

open access: yesThe Astrophysical Journal Letters
Stellar obliquity serves as a key diagnostic for tracing the dynamical evolution of bound systems—from giant planets and brown dwarfs to stellar binaries—revealing whether these diverse populations share analogous histories.

X-Shooter Medium Resolution Brown Dwarfs Library [PDF]

open access: yes, 2015
} We obtain medium-resolution spectra in the optical (550-1000 nm, R̃5400) and the near-infrared (1000-2500 nm, R̃3300) using the Wideband ultraviolet-infrared single target spectrograph (X-Shooter) at the Very Large Telescope (VLT).

Activity of protostars and brown dwarfs

open access: yes, 2003
The first evidences for magnetic activity in low-mass protostars and brown dwarfs were found in the mid-1990's by the old generation of X-ray satellites, namely ROSAT and ASCA.
