How Green Banks can create multiple types of value in the transition to net zero emissions

Australian Journal of Public Administration, EarlyView., 2023
Abstract Current levels of investment are insufficient to meet the goals of the Paris Agreement, and private sector funding shortfalls are acute. Despite this, little research has been undertaken into Green Banks, a new form of institution which mixes public and private institutional logics to mobilise additional private investment in the net zero ...

From ambivalence to vulnerability: Recognition and the subject

Journal for the Theory of Social Behaviour, Volume 52, Issue 4, Page 595-608, December 2022., 2022
Abstract Recent writings on recognition and ambivalence highlight the limits of narrowly dyadic and teleological accounts of recognition. In this article, I extend the work on ambivalent recognition by proffering a conception of recognition as vulnerable.

Positron flux and γ-ray emission from Geminga pulsar and pulsar wind nebula [PDF]

Monthly notices of the Royal Astronomical Society, 2018
Nearby pulsars have been suggested as sources of $\sim$TeV $e^+/e^-$ Cosmic Ray (CR) excess on Earth. The High-Altitude Water Cherenkov Observatory (HAWC) detected extended TeV emission regions in the direction of two nearby middle-aged pulsars, Geminga ...

The Spatial and Emission Properties of the Large [O iii] Emission Nebula Near M31

The Astrophysical Journal, 2023
Drechsler et al. reported the unexpected discovery of a 1.°5 long [O iii ] emission nebula 1.°2 southeast of the M31 nucleus. Here we present additional images of this large emission arc, called the Strottner–Drechsler–Sainty Object (SDSO), along with ...

Detection of polarized gamma-ray emission from the Crab nebula with the Hitomi Soft Gamma-ray Detector† [PDF]

Nippon Tenmon Gakkai obun kenkyu hokoku, 2018
We present the results from the Hitomi Soft Gamma-ray Detector (SGD) observation of the Crab nebula. The main part of SGD is a Compton camera, which in addition to being a spectrometer, is capable of measuring polarization of gamma-ray photons.

Erratum: Modelling the ArH+ emission from the Crab Nebula [PDF]

Monthly notices of the Royal Astronomical Society, 2017
We have performed combined photoionization and photodissociation region (PDR) modelling of a Crab Nebula filament subjected to the synchrotron radiation from the central pulsar wind nebula, and to a high flux of charged particles; a greatly enhanced ...

Mapping NGC 7027 in New Light: CO+ and HCO+ Emission Reveal Its Photon- and X-Ray-dominated Regions

The Astrophysical Journal, 2022
The young and well-studied planetary nebula (PN) NGC 7027 harbors significant molecular gas that is irradiated by luminous, pointlike UV (central star) and diffuse (shocked nebular) X-ray emission.
