The binary fraction of red supergiants in the Magellanic Clouds
Min Dai and others
Monthly Notices of the Royal Astronomical Society, Volume 539, Issue 2, May 2025, Pages 1220–1235, https://doi.org/10.1093/mnras/staf560
Red supergiants (RSGs), as the descendants of OB-type stars and the progenitors of supernovae, provide crucial insights into the evolution of massive stars, particularly in binary systems. Previous studies show that the binary fraction of RSGs ( $\approx 15\!-\!40~{{\ \rm per\ cent}}$ ) is ...
Energy-resolved polarization study of the Crab nebula with IXPE
Wenhao Wei and others
Monthly Notices of the Royal Astronomical Society, Volume 539, Issue 2, May 2025, Pages 902–909, https://doi.org/10.1093/mnras/staf538
This work presents a new detailed study on the energy-dependent variation in the X-ray polarization of the Crab pulsar wind nebula (PWN), obtained using data from the Imaging X-ray Polarimetry Explorer ( IXPE ). For the entire PWN, we observed a linear variation in polarization degree (PD), and ...
Exploring the fate of primordial discs in Milky Way-sized galaxies with the GigaEris simulation
Floor van Donkelaar and others
Monthly Notices of the Royal Astronomical Society, Volume 539, Issue 2, May 2025, Pages 1259–1268, https://doi.org/10.1093/mnras/staf597
Recent observations with JWST and Atacama Large Millimeter/submillimeter Array (ALMA) have unveiled galaxies with regular discs at significantly higher redshifts than previously expected. This appears to be in contrast to our understanding of galaxy evolution at high redshift. Additionally, the ...
Life in the slow lane: a search for long-term variability in ASAS-SN
Sydney Petz and C S Kochanek
Monthly Notices of the Royal Astronomical Society, Volume 539, Issue 2, May 2025, Pages 1065–1076, https://doi.org/10.1093/mnras/staf587
We search a sample of 9361 613 isolated sources with 13< g <14.5 mag for slowly varying sources. We select sources with brightness changes larger than $\sim 0.03$ mag yr −1 over 10 yr, removing false positives due to, for example, nearby bright stars or high proper motions. After a thorough ...
The Herschel-SPIRE Dark Field – II. A P(D) fluctuation analysis of the deepest Herschel image of the submillimetre universe
Thomas W O Varnish and others
Monthly Notices of the Royal Astronomical Society, Volume 539, Issue 1, May 2025, Pages 347–354, https://doi.org/10.1093/mnras/staf318
The Herschel -SPIRE Dark Field is the deepest field produced by the SPIRE instrument pushing down below the galaxy confusion limit in each of the 250, 350, 500 $\mu$ m bands. Standard source extraction techniques inevitably fail because of this, and we must turn to statistical methods. Here, we ...
The Herschel-SPIRE Dark Field I: the deepest Herschel image of the submillimetre Universe
Chris Pearson and others
Monthly Notices of the Royal Astronomical Society, Volume 539, Issue 1, May 2025, Pages 336–346, https://doi.org/10.1093/mnras/staf335
We present the image maps, data reduction, analysis, and the first source counts from the Herschel SPIRE Dark Field. The SPIRE Dark Field is an area of sky near the North Ecliptic Pole observed many times during the calibration phase of the Herschel mission in order to characterize the stability of ...
Three new 2+2 quadruple systems with changing inclination
P Zasche and others
Monthly Notices of the Royal Astronomical Society, Volume 539, Issue 2, May 2025, Pages 1015–1023, https://doi.org/10.1093/mnras/staf495
We present a unique discovery of three new detected systems showing two different phenomena together. These are 2+2 quadruple stellar systems showing two eclipsing binaries as the inner pairs. And besides that, these systems were also found to exhibit the precession of the inner orbits causing the ...
The relation of galaxies and dark matter haloes to the filamentary cosmic web
Navdha and others
Monthly Notices of the Royal Astronomical Society, Volume 539, Issue 2, May 2025, Pages 1248–1258, https://doi.org/10.1093/mnras/staf578
We use the Millennium Simulation to study the relation of galaxies and dark matter haloes to the cosmic web. We define the web as the unique, fully connected, percolating object with (unsmoothed) matter density everywhere exceeding 5.25 times the cosmic mean. This object contains 35 per cent of all ...
