Mass-23 nuclei in astrophysics by Fraser, Paul, Amos, K., Canton, L., Karataglidis, S., Svenne, J., Van Der Kniff, D.

“…The formation of mass-23 nuclei by radiative capture is of great interest in astrophysics. A topical problem associated with these isobars is the so-called 22Na puzzle of ONe white dwarf novae, where the abundance of 22Na observed is not as is predicted by current stellar models, indicating there is more to learn about how the distribution of elements in the universe occurred. …”

Indirect methods in nuclear astrophysics by Bertulani, C., Shubhchintak, Mukhamedzhanov, A., Kadyrov, Alisher, Kruppa, A., Pang, D.

“…We discuss recent developments in indirect methods used in nuclear astrophysics to determine the capture cross sections and subsequent rates of various stellar burning processes, when it is difficult to perform the corresponding direct measurements. …”

Transient Astrophysics with the Square Kilometre Array by Fender, R., Stewart, A., Macquart, Jean-Pierre, Donnarumma, I., Murphy, T., Deller, A., Paragi, Z., Chatterjee, S.

“…This chapter provides an overview of the possibilities for transient and variable-source astrophysics with the Square Kilometre Array. While subsequent chapters focus on the astrophysics of individual events, we focus on the broader picture, and how to maximise the science coming from the telescope. …”

Confronting astrophysical uncertainties in the direct detection of dark matter by Kavanagh, Bradley James

“…Finally, we propose a method of extending this parametrisation to directional data, which should allow even more information to be extracted from future experiments without the need for astrophysical assumptions.…”

WIMP particle physics and astrophysics with direct detection and neutrino telescope data by Kavanagh, Bradley James, Fornasa, Mattia, Green, Anne M.

“…Recent work has shown that, with a polynomial parameterisation of the WIMP speed dis- tribution, it is possible to make an unbiased measurement of the WIMP mass, without making any astrophysical assumptions. However, direct detection experiments are not sensitive to low-speed WIMPs and, therefore, any model-independent approach will lead to a bias in the cross section. …”
