Type Ia supernova diversity: Standardizing the candles [PDF]
, 2007 Future use of type Ia supernovae for cosmology aims not only to determine the equation of state of dark energy, but also to constrain possible variations in its value.

The Extremes of Thermonuclear Supernovae [PDF]
, 2017 The majority of thermonuclear explosions in the Universe seem to proceed in a rather standardised way, as explosions of carbon-oxygen (CO) white dwarfs in binary systems, leading to 'normal' Type Ia supernovae (SNe Ia).

Astronomische Nachrichten, Volume 347, Issue 1, January 2026.ABSTRACT We present new radial velocity measurements of 13 selected intermediate mass stars (2–6 M⊙). The measurements were performed between 29 April and 6 September 2024 at the University Observatory Jena using the échelle spectrograph FLECHAS. The radial velocity of eight stars was found to be constant during our spectroscopic monitoring, namely: 17

The Carnegie Supernova Project: First Photometry Data Release of Low-Redshift Type Ia Supernovae [PDF]
, 2009 The Carnegie Supernova Project (CSP) is a five-year survey being carried out at the Las Campanas Observatory to obtain high-quality light curves of ~100 low-redshift Type Ia supernovae in a well-defined photometric system.

Nachtsicht ins All mit dem bloßen Auge: Sag mir, wie weit die Sterne steh'n
Physik in unserer Zeit, Volume 57, Issue 1, Page 32-40, January 2026.Beim Blick in den Nachthimmel sehen wir ohne optische Hilfsmittel und abhängig von der lokalen Lichtverschmutzung viele Hundert bis maximal einige Tausend Sterne und auch einige Galaxien. Aber wie weit sind diese von uns entfernt? Und bis zu welchen maximalen Entfernungen können wir Objekte im Weltall mit dem bloßen Auge wahrnehmen?

A Susy Phase Transition as Central Engine [PDF]
, 2005 For several decades the energy source powering supernovae and gamma ray bursts has been a troubling mystery. Many articles on these phenomena have been content to model the consequences of an unknown "central engine" depositing a large amount of energy ...

Supernova 1988A: another clumped supernova [PDF]
Monthly Notices of the Royal Astronomical Society, 1991 The evolution of the forbidden multiplet (1F) oxygen lines in the optical spectrum of SN 1988A is used to determine the evolution of the optical depth in those transitions which in turn can be used to derive the number density of oxygen in the ejecta.

Cherenkov Telescope Array Observatory: Die Zukunft der Gammaastronomie
Physik in unserer Zeit, Volume 57, Issue 1, Page 10-18, January 2026.Im Jahr 1989 hat das Wipple‐Observatorium die erste Quelle hochenergetischer Gammastrahlung entdeckt. 2002 waren dann sechs Quellen bekannt, 2024 schon mehr als 300. Und das ist immer noch lediglich die Spitze des Eisbergs in der jungen Geschichte der Gammaastronomie.
