Topic: black holes

Ore Gottlieb’s group studies compact objects and high-energy transients through general-relativistic magnetohydrodynamic simulations, analytical models and multimessenger predictions. Topics include black holes, neutron stars, collapsars, stellar explosions, compact-object mergers, gamma-ray bursts, nucleosynthesis and gravitational waves. The researcher can develop independent projects and use leadership-class computing allocations. The benefits-eligible appointment is for two years with a possible third year, beginning flexibly in summer or autumn 2027. Salary is $73,308–$90,000. Application

Laura Blecha’s group recruits a researcher to study supermassive black holes, gravitational-wave and multimessenger source populations, and the cosmic evolution of black holes and galaxies. The preferred start is 16 August 2027. The appointment renews annually for two years, with a possible third year subject to performance and funding. It provides a $60,000 salary, travel funding, benefits and access to the HiPerGator computing cluster. Applications received by 4 December 2026 receive full consideration; the listed closing date is 28 February 2027.

Three-year research positions allowing early-career astrophysicists to develop an independent programme while collaborating with MPA researchers. Areas include stars and stellar systems, supernovae, gravitational waves, galaxy formation, black holes and cosmology. Fellows have access to computing facilities and support for scientific travel. Gross annual salary is stated as approximately EUR 67,500–77,700 depending on experience, with public-service benefits. Apply by 15 November 2026 with a CV, publication list, research statement and three referees; reference letters are due on the same date

Saavik Ford gives a public lecture in the Simons Foundation's 2026 Black Holes series, which examines black holes from stellar remnants to supermassive galactic objects through observational breakthroughs and theoretical advances.

Vitor Cardoso discusses how observations and theory are changing black-hole physics. The conversation covers Hawking radiation, general relativity, gravitational-wave observations and the Event Horizon Telescope, asking what these measurements reveal about black holes and what future observatories could test.

Ulrich Sperhake and Seppe Staelens explain hypothetical boson stars and how researchers use mathematical modelling to investigate them. The discussion connects these unusual compact objects to black holes, gravity and gravitational-wave observations.

Øyvind Grøn discusses black holes, their prediction by relativity and the observations used to study them. Conversation in Norwegian.

How can black holes be established both as a consequence of gravitational theory and as objects in the sky? Roger Penrose examines the mathematical development of gravitational collapse and space-time singularities, explaining why black-hole formation does not depend on perfectly symmetric idealisations. Reinhard Genzel and Andrea Ghez trace the observational effort to establish a massive compact object at the centre of the Milky Way. Their accounts connect infrared observations, improvements in imaging through atmospheric distortion, and long-term measurements of stellar motions around Sagitt
