Baryonic mass budgets in the central regions of the Bullet Cluster and their consistency with strong lensing in MOND
Dong Zhang, Hosein Haghi, Elena Asencio +8
Strong lensing observations of the Bullet Cluster have traditionally been regarded as strong evidence for dark matter and a major challenge to Milgromian dynamics (MOND). The offse…
The Sc, Ti, and V Abundance Discrepancy: Testing High-Mass IMF Variation and Massive-Star Rotation
Soonchul Choi, Eda Gjergo, Youngman Kim +1
Scandium, titanium, and vanadium can be synthesized primarily in massive stars. Yet many of the current Galactic chemical evolution models under-produce these elements at early epo…
Limited imprint of high-mass IMF variations on sodium abundances in main-sequence galaxies
Ziyi Guo, Donatella Romano, Zhiqiang Yan +10
Growing evidence suggests that the stellar initial mass function (IMF) varies systematically across galaxies, deviating from the canonical Milky Way form. Such variations would mod…
The mmax-Mecl relation in the LEGUS clusters
Marie Zinnkann, Tereza Jerabkova, Zhiqiang Yan +6
The relation between the maximum stellar mass in a very young cluster (mmax) and the total stellar mass of the cluster (Mecl), known as the mmax-Mecl relation, remains debated in t…
The Initial Mass Function as the Equilibrium State of a Variational Process: why the IMF cannot be sampled stochastically
Eda Gjergo, Zhiyu Zhang, Pavel Kroupa
The stellar initial mass function (sIMF) is often treated as a stochastic probability distribution, yet such an interpretation implies Poisson noise that is inconsistent with growi…
Massive Star Formation at Supersolar Metallicities: Constraints on the Initial Mass Function
Eda Gjergo, Zhiyu Zhang, Pavel Kroupa +6
Metals enhance the cooling efficiency of molecular clouds, promoting fragmentation. Consequently, increasing the metallicity may boost the formation of low-mass stars. Within the i…
The effect of the environment-dependent stellar initial mass function on the baryonic Tully Fisher relation
Akram Hasani Zonoozi, Hosein Haghi, Pavel Kroupa +4
We investigate the impact of an environment-dependent galaxy-wide stellar initial mass function (gwIMF) on the baryonic Tully-Fisher relation (BTFR). The integrated galaxy-wide IMF…
Alien Type Ia supernovae from the Milky Way merger history and one possible candidate: Kepler's supernova
Wenlang He, Ping Zhou, Eda Gjergo +1
The Milky Way is a dynamic and evolving system shaped by numerous merger events throughout its history. These mergers bring stars with kinematic and dynamic properties differing fr…
The Impact of Early Massive Galaxy Formation on the Cosmic Microwave Background
Eda Gjergo, Pavel Kroupa
The Cosmic Microwave Background (CMB) anisotropies, corrected for foreground effects, form the foundation of cosmology and support the Big Bang model. A previously overlooked foreg…
The p-Laplacian as a Framework for Generalizing Newtonian Gravity and MoND
D. Scherer, J. Pflamm-Altenburg, P. Kroupa +1
The Radial Acceleration Relation (RAR) follows from Milgromian gravitation (MoND). Velocity dispersion data of many dwarf spheroidal galaxies (dSphs) and galaxy clusters have been…
