    The Extraordinary Long-lasting Infrared Echo of PS16dtm Reveals an Extremely Energetic Nuclear Outburst by Ning Jiang, Di Luo, Jiazheng Zhu, Roc M. Cutri

    Published 2025-01-01
    “…This work highlights the distinctive value of IR echoes in measuring the accurate intrinsic bolometric luminosity and thus the total radiated energy of TDEs, which could be severely underestimated by traditional methods, i.e., probably by more than 1 order of magnitude in PS16dtm. …”

    Multimessenger Probes of Supermassive Black Hole Spin Evolution by Angelo Ricarte, Priyamvada Natarajan, Ramesh Narayan, Daniel C. M. Palumbo

    Published 2025-01-01
    “…We compare several variations of our model with compiled black hole (BH) spin measurements derived from X-ray reflection spectroscopy, correcting for a bias arising from the spin-dependent radiative efficiency of accretion flows. We show that the observed spin distribution is in agreement with a model that includes jet-driven spin-down, a key mechanism that acts to modulate spins across cosmic time at both high and very low specific accretion rates. …”

    Synthesis and optical properties of LaSrGaO4:RE3+ (RE = Sm, Eu, Ho) single crystals via optical float zone method by Hasan Yilmaz, Masahiko Isobe, Oliver Clemens, Markus Suta, Pascal Puphal

    Published 2025-02-01
    “…Photoluminescence studies at both 77 K and 298 K reveal that the incorporated lanthanoid ions brightly emit and even show unusual transitions due to the low cutoff phonon energy of the host compound that limits non-radiative loss pathways. Together with a high physical density of ∼6.4 g/cm3, these phosphors could be conceptualized as interesting candidates for X-ray imaging phosphors aiming at high light yields.…”

    Using a region-specific ice-nucleating particle parameterization improves the representation of Arctic clouds in a global climate model by A. B. Gjelsvik, R. O. David, T. Carlsen, F. Hellmuth, S. Hofer, Z. McGraw, Z. McGraw, H. Sodemann, H. Sodemann, T. Storelvmo, T. Storelvmo

    Published 2025-02-01
    “…Ice-nucleating particles (INPs) are necessary for primary cloud ice formation at temperatures above approximately <span class="inline-formula">−</span>38 °C and thus significantly affect cloud phase and cloud radiative effect (CRE). Due to their complex and insufficiently understood variability, INPs constitute an important modelling challenge, especially in remote regions with few observations, such as the Arctic. …”

    Synthetic Modeling of Polarized Dust Emission in Intermediate-mass YSOs. I. Constraining the Role of Iron Inclusions and Inelastic Relaxation on Grain Alignment with ALMA Polarizat... by Nguyen Chau Giang, V. J. M. Le Gouellec, Thiem Hoang, A. J. Maury, P. Hennebelle

    Published 2025-01-01
    “…Iron inclusions embedded inside dust grains play a crucial role in both internal alignment (IA) via Barnett relaxation and external alignment via the MAgnetically Enhanced RAdiative Torque (MRAT) mechanism. Moreover, inelastic relaxation is predicted to dominate over Barnett relaxation in driving the IA of micron-sized grains and very large grains (VLGs) above 10 μ m. …”
