Improving the accuracy of food security predictions by integrating conflict data

Autor: Bertetti, Marco, Agnolucci, Paolo, Calzadilla, Alvaro, Capra, Licia

Violence and armed conflicts have emerged as prominent factors driving food crises. However, the extent of their impact remains largely unexplored. This paper provides an in-depth analysis of the impact of violent conflicts on food security in Africa

We present a catalog of 689 galaxy cluster candidates detected at significance $\xi>4$ via their thermal Sunyaev-Zel'dovich (SZ) effect signature in 95 and 150 GHz data from the 500-square-degree SPTpol survey. We use optical and infrared data from t

SPT-CL J2215-3537: A Massive Starburst at the Center of the Most Distant Relaxed Galaxy Cluster

Autor: Calzadilla, Michael S., Bleem, Lindsey E., McDonald, Michael, Gladders, Michael D., Mantz, Adam B., Allen, Steven W., Bayliss, Matthew B., Eilers, Anna-Christina, Floyd, Benjamin, Hlavacek-Larrondo, Julie, Khullar, Gourav, Kim, Keunho J., Mahler, Guillaume, Sharon, Keren, Somboonpanyakul, Taweewat, Stalder, Brian, Stark, Antony A.

We present the discovery of the most distant, dynamically relaxed cool core cluster, SPT-CL J2215-3537 (SPT2215) and its central brightest cluster galaxy (BCG) at z=1.16. Using new X-ray observations, we demonstrate that SPT2215 harbors a strong cool

A luminous dust-obscured Tidal Disruption Event candidate in a star forming galaxy at 42 Mpc

While the vast majority of Tidal Disruption Events (TDEs) has been identified by wide-field sky surveys in the optical and X-ray bands, recent studies indicate that a considerable fraction of TDEs may be dust obscured, and thus preferentially detecte

We present a multi-wavelength analysis of the galaxy cluster SPT-CL J0607-4448 (SPT0607), which is one of the most distant clusters discovered by the South Pole Telescope (SPT) at $z=1.4010\pm0.0028$. The high-redshift cluster shows clear signs of be
