Observations of the fluctuations in Interplanetary Magnetic Field around L1 point during the solar transient events of 2024 with MAG payload onboard Aditya-L1 spacecraft
The MAG payload onboard India's first solar mission, Aditya-L1, is a dual-senssor fluxgate magnetometer designed to measure th interplanetary magnetic field (IMF) while operating in a halo orbit around the first Sun-Earth Lagrangian point (l1). Since becoming operational in January 2024, MAG has continuously recorded local magnetic field data and has captured several solar transient events over the past one year. During these events, the IMF, typically around 5 nT, exhibited significant enhance…

I currently read “It can’t happen here” by Sinclair Lewis from 1935. It's about fictive events in the US in 1936: an election won by a senator turned dictator. It reads like a description of the US 2024/2025, except dear leader is Democrat, not Republican. I'm on page 90 (just finished chapter 11), almost 300 more to read, it really is hard!
As the Trump playbook follows Project 2025, are we completely sure that this is NOT just a rewrite of Lewis' novel?

Six microlensing planets detected via sub-day signals during the 2023 -- 2024 season
We present analyses of six microlensing events: KMT-2023-BLG-0548, KMT-2023-BLG-0830, KMT-2023-BLG-0949, KMT-2024-BLG-1281, KMT-2024-BLG-2059, and KMT-2024-BLG-2242. These were identified in KMTNet data from the 2023 -- 2024 seasons, selected for exhibiting anomalies shorter than one day -- potential signatures of low-mass planetary companions. Detailed modeling of the light curves reveals that the anomalies in all six events are caused by planetary companions to the lenses. The brief durations…

Engaging and Educating Eclipse Observers Through Workshops, Media, Planetarium shows and Citizen Science
The Heliophysics Big Year was an extended year where major solar events engaged the public. It included two eclipses (annular on October 14, 2023 and total on April 8, 2024), plus solar max and the Parker Solar Probe perihelion December 24, 2024. After the eclipse of 2017, many millions more Americans planned to view the solar corona. We expanded our eclipse website with activities, citizen science projects, resources, training videos, equipment, and external links. We were the Southwest Region…

Three binary-source binary-lens microlensing events from the 2024 microlensing campaign
We investigated microlensing events detected by the OGLE and KMTNet surveys during the 2024 observing season, focusing on those that exhibit very complex anomaly features. Through this analysis, we found that the light curves of three events including OGLE-2024-BLG-0657, KMT-2024-BLG-2017, and KMT-2024-BLG-2480 cannot be readily interpreted using standard three-body lensing models such as a binary lens with a single source (2L1S) or a single lens with a binary source (1L2S). In this work we pre…

Terrorism & Democracy in Burkina-Faso
This article examines the political consequences of terrorism in Burkina Faso. Using a dataset combining geolocated terrorist events from ACLED (from 2015 to 2024) with public opinion data from Afrobarometer, I compare the effect of successful terrorist attacks on public support for democracy and authoritarian alternatives. The results reveal that successful terrorist attacks significantly increase support for military regimes, one man regimes, and one party systems, while decreasing support fo…

Flare energetics, CME launch and heliospheric propagation for the May 2024 events, as derived from ensemble MHD modelling
Many questions must be answered before understanding the relationship between the emerging magnetic flux through the solar surface and the extreme geoeffective events. The main ingredients for getting X-ray class flares and large interplanetary Coronal Mass Ejections (CMEs) are the build-up of electric current in the corona, the existence of magnetic free energy, magnetic energy/helicity ratio, twist, and magnetic stress in active regions (ARs). The upper limit of solar energy in the space rese…

Investigation of Low-Energy Particle Remnants in High-Energy Collisions at the LHC with a Skipper-CCD detector
We deployed MOSKITA $\sim$33 m away from the CMS collision point, the first skipper-CCD detector probing low-energy particles produced in high-energy collisions at the Large Hadron Collider (LHC). In this work, we search for beam-related events using data collected in 2024 during beam-on and beam-off periods. The dataset corresponds to integrated luminosities of 113.3 fb$^{-1}$ and 1.54 nb$^{-1}$ for the proton-proton and Pb-Pb collision periods, respectively. We report observed event rates in …

Pre-perihelion radio observations of comet 12P/Pons-Brooks with Tianma radio telescope
{The multiple outburst events of comet 12P/Pons-Brooks during its 2024 apparition offer a unique window into highly-active volatile releasing processes not observable during quiescent periods. We performed radio observations of comet 12P/Pons-Brooks with the Tianma-65m radio telescope, targeting the OH and NH$_3$ inversion lines at 18-cm and 1.3-cm, respectively. By monitoring 12P at different heliocentric distances on its inbound journey, we aim to provide insights into the comet's volatile co…

Geopolitical Barriers to Globalization
This paper systematically estimates and quantifies how geopolitical alignment shapes global trade across three distinct eras: the Cold War, hyper-globalization, and contemporary fragmentation. We construct a novel measure of bilateral alignment using large language models to compile and analyze 833,485 political events spanning 193 countries from 1950 to 2024. Our analysis reveals that trade flows systematically track geopolitical alignment in both bilateral relationships and aggregate patterns…
