Blue Large-Amplitude Pulsators and Other Short-Period Variable Stars in OGLE-IV Fields of the Outer Galactic Bulge
J. Borowicz, P. Pietrukowicz, J. Skowron +13
In this work, we search the OGLE-IV outer Galactic bulge fields for short-period variable objects. The investigation focuses on unexplored timescales roughly below one hour in an a…
KMT-2023-BLG-1866Lb: Microlensing super-Earth around an M dwarf host
Cheongho Han, Ian A. Bond, Andrzej Udalski +64
We investigate the nature of the short-term anomaly that appears in the lensing light curve of KMT-2023-BLG-1866. The anomaly was only partly covered due to its short duration, les…
Magnetic effects in the Hadron Resonance Gas
Michał Marczenko, Michał Szymański, Pok Man Lo +4
We discuss the modeling of the hadronic phase of QCD at finite magnetic field in the framework of hadron resonance gas (HRG). We focus on the statistical description of particle yi…
OGLE-2018-BLG-0971, MOA-2023-BLG-065, and OGLE-2023-BLG-0136: Microlensing events with prominent orbital effects
Cheongho Han, Andrzej Udalski, Ian A. Bond +60
We undertake a project to reexamine microlensing data gathered from high-cadence surveys. The aim of the project is to reinvestigate lensing events with light curves exhibiting int…
Discovery of the Longest-Period Classical Cepheid in the Milky Way
I. Soszyński, D. M. Skowron, A. Udalski +12
We report the discovery of the classical Cepheid OGLE-GD-CEP-1884 (= GDS_J1535467-555656) with the longest pulsation period known in our Galaxy. The period of 78.14 d is nearly 10…
Virial Black Hole Masses for AGNs behind the Magellanic Clouds
Swayamtrupta Panda, Szymon Kozłowski, Mariusz Gromadzki +13
We use the spectroscopic data collected by the Magellanic Quasars Survey (MQS) as well as the photometric V- and I-band data from the Optical Gravitational Lensing Experiment (OGLE…
OGLE-2023-BLG-0836L: The sixth microlensing planet in a binary stellar system
Cheongho Han, Andrzej Udalski, Youn Kil Jung +32
Light curves of microlensing events occasionally deviate from the smooth and symmetric form of a single-lens single-source event. While most of these anomalous events can be accoun…
KMT-2023-BLG-0416, KMT-2023-BLG-1454, KMT-2023-BLG-1642: Microlensing planets identified from partially covered signals
Cheongho Han, Andrzej Udalski, Chung-Uk Lee +32
We investigate the 2023 season data from high-cadence microlensing surveys with the aim of detecting partially covered short-term signals and revealing their underlying astrophysic…
Systematic KMTNet Planetary Anomaly Search. XI. Complete Sample of 2016 Sub-Prime Field Planets
In-Gu Shin, Jennifer C. Yee, Weicheng Zang +63
Following Shin et al. (2023b), which is a part of the Systematic KMTNet Planetary Anomaly Search series (i.e., a search for planets in the 2016 KMTNet prime fields), we conduct a s…
OGLE-2017-BLG-0448Lb: A Low Mass-Ratio Wide-Orbit Microlensing Planet?
Ruocheng Zhai, Radosław Poleski, Weicheng Zang +38
The gravitational microlensing technique is most sensitive to planets in a Jupiter-like orbit and has detected more than 200 planets. However, only a few wide-orbit () micro…
Influence of dynamical screening of four-quarks interaction on the chiral phase diagram
Michał Szymański, Pok Man Lo, Krzysztof Redlich +1
We investigate the effect of screening of the four-quarks contact interactions by the ring diagram at finite temperature and density in an effective chiral model inspired by QCD in…
OGLE-2017-BLG-1186: first application of asteroseismology and Gaussian processes to microlensing
Shun-Sheng Li, Weicheng Zang, Andrzej Udalski +102
We present the analysis of the event OGLE-2017-BLG-1186 from the 2017 Spitzer microlensing campaign. This is a remarkable microlensing event because its source is photometrically b…
