This paper advances current debates about feminist methodologies in geography by attending to affectual intensities and their resonance. Affectual intensities emerge through encounters between different bodies and objects, and are deeply power-laden, enabling, disabling, transforming, and restricting geographic research. We attend to three moments of resonance that surfaced in Elisabeth Militz's field research on nationalism in Azerbaijan. In each, we show how attending to affectual intensities reveals much about the work of power in nationalism and in the constitution of geographic knowledge about it. The paper calls for an affectual methodology, a process of critical writing, reflection, and rewriting about moments of resonance between different bodies and objects in the field, and as we analyse, present, and write up our data. This is a layered, dialogic, and collaborative writing strategy that, we argue, enables us to write through and with affect. In particular, our work contributes a nuanced and multi-layered approach to uncover often-neglected power structures of predominantly white and heteronormative geographic research practice.

Ahmed's (2014) idea of "stickiness" or McKittrick's (2006) work on "bodymemory" (see also Crawford, 2018b) conceptualise how research encounters are always emotion-laden and imbued with power, reproducing and legitimating social hierarchy. We, as researchers, must recognise and critically reflect on the long histories of power relations in our, seemingly innate, gut feelings. Yet, how to navigate this terrain methodologically?In this paper we build on Noxolo's call to "'write' the body both as a social, political and economic location and as a sensory agent" (2009, p. 63; emphasis in original). We suggest a methodological intervention that centres layered, dialogic, and collaborative writing. We describe this as an affectual methodology by fusing the affective with the emotional (see also Tolia-Kelly, 2006). In so doing, our intervention forms part of a wider conceptual move to bridge intellectual divides between geographies of affect, informed by non-representational theory and feminist emotional geographies (see for example, Colls, 2012;Schurr, 2014). With Noxolo, Ahmed, and others, we understand an affectual methodology as the outcome of "how we come into contact with objects and others" (Ahmed, 2014, p. 208). Thus, how we produce, handle,
