The reliability of gas-phase metallicities immediately adjacent to non-star-forming spaxels in MaNGA
No full textIn this work, we use gas phase metallicities calculated from the Sloan Digital Sky Survey (SDSS) Mapping Nearby Galaxies at Apache Point (MaNGA) Data Release 17 (DR17) to assess the extent of potential biases in spaxels which are spatially adjacent to spaxels identified as non-star forming (non-SF) on a BPT diagram. We identify a sample of such spaxels with calculable metallicities from the full metallicity catalogue (1.57 million), representing a small fraction ( percent) of the full metallicity sample. 23 percent of all galaxies with at least one spaxel with a calculable metallicity also contain at least one spaxel with a calculated metallicity adjacent to a non-SF spaxel, with a typical galaxy hosting 9 non-SF-adjacent spaxels. From our suite of 6 different metallicity calibrations, we find that only the metallicity calibrations based entirely on the [NII]/Hα ratio are affected, showing systematic offsets to higher metallicities by up to 0.04 dex if they are located adjacent to a non-SF flagged spaxel, relative to a radially matched control sample. The inclusion of additional diagnostic diagrams (based on [OI] and/or [SII]) is insufficient to remove the observed offset in the [NII]/Hα based calibrations. Using a stricter diagnostic line on the BPT diagram removes 94 percent of identified bordering spaxels with metallicities for all metallicity calibrations, and removes the residual offset to higher metallicity values seen in [NII]/Hα calibrations. If science cases demand an exceptionally clean metallicity sample, we recommend either a stricter BPT cut, and/or a non-[NII]/Hα based metallicity calibration
Blerds of a Feather, Nerd Out Together: Exploring Sociological Intersections of Black Identity and Nerd Culture
No full textBlack nerds, or “Blerds,” exist at the intersection of nerd identity and Black racial identity. In recent years, however, Blerds have built communities and events that celebrate both aspects of their identity. However, mainstream (predominantly white) nerd culture and societal stereotypes of Blackness often position these identities as conflicting, leaving Blerds to navigate a unique middle ground. This study explores how Blerds embrace both identities despite these tensions. Based on semi-structured interviews with 18 self-identified Blerds, the research examines how they negotiate their racial and nerd identities, how other identities intersect, and how they challenge norms around race and nerd culture. My findings highlight that Blerds actively resist stereotypes, creating spaces where Blackness and nerdiness coexist in ways that defy societal expectations. This study contributes to intersectionality research by demonstrating how identity is constructed at the crossroads of race and subculture, positioning the Blerd community as a site of joy, resistance, and belonging
Bodily Representations, Transformative Imaginations: Queerness in the Contemporary Chinese Experimental Art of Ma Liuming and Chi Peng
No full textMa Liuming’s Fen-Ma Liuming performances and Chi Peng’s photo series Consubstantiality and I Fuck Me each depict the artist’s own naked body engaged in acts of defiance, from queer sex to questioning binaries of gender and nation. Ma Liuming’s performance works present the binaries of male/female and socialist/capitalist as fluid and blended, queering both himself and the state of China; Chi Peng’s series I Fuck Me forwards a productive critique of personal identity’s relevance in public culture through its engagement with transnational queer politics. Each artist challenges the dominating pressures of normativity and expresses queerness as a mode of existence that resists binary interpretations. Their art reflects expansive expressions of gender and sexuality that serve to problematize postsocialist China’s transformation into a neoliberal state, further demonstrating that the evolution of queerness in Chinese experimental art and China’s development in the era of reforms (post-1978) are intertwined. This paper will illuminate how contemporary Chinese experimental artists use their bodies to create queer expressions that challenge the dominating pressures of heteronormativity, destabilize conformity, and transcend binaries within the developing social and physical landscape of postsocialist Beijing, reflecting the expansive nature of late-20th-century China’s unprecedented urbanization, social change, and economic development
